  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The nanoantennas are arranged as arrays of asymmetric-split H-shape (ASH) structures, tuned to produce plasmonic resonances with reflectance double peaks within the mid-infrared vibrational resonances of C-H bonds for the assay of deposited films of the molecule 17β-estradiol (E2), used as an analyte.
  • Measurements and numerical simulations of the reflectance spectra have enabled an estimated enhancement factor on the order of 10<sup>5</sup> to be obtained for a thin film of E2 on the ASH array.
  • A high sensitivity value of 2335 nm/RIU was achieved, together with a figure of merit of approximately 8.
  • Our experimental results were corroborated using numerical simulations for the C-H stretch vibrational resonances from the analyte, superimposed on the plasmonic resonances of the ASH nanoantennas.

  • [Title] Isotopic and nonisotopic assays for measuring somatotropin compared: re-evaluation of cutoff value in provocative tests.
  • Serum hGH can be measured by various immunoassays, isotopic and nonisotopic, with monoclonal or polyclonal antibodies: a cutoff value of 10 micrograms/L after provocative testing is usually used to distinguish normal from hGH-deficient children.
  • Here we evaluated the responses of six different commercial assays, radioisotopic and nonisotopic, with monoclonal or polyclonal antibodies in a series of 16 provocative tests (stimulation with clonidine) in short children.
  • A wide range of discrepant values was obtained with the different kits.
  • A cutoff of 10 micrograms/L produced discordance of diagnosis among assays for two children, whereas complete agreement was reached for a cutoff value of 7 micrograms/L.
  • Cutoff values and reference values must be established separately for each method proposed for routine use.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Analytical performance and diagnostic accuracy of six different faecal calprotectin assays in inflammatory bowel disease.
  • Analytical performance (imprecision, accuracy, carry-over, correlation and agreement) and diagnostic accuracy (sensitivity, specificity, likelihood ratios) of the different assays were evaluated.
  • RESULTS: All methods demonstrated good analytical performance, but within-run and total imprecision varied depending on the assay methodology used.
  • Using Passing Bablok and Bland-Altman analyses, low quantitative agreement was observed between the assays.
  • All assays showed excellent diagnostic accuracy, with areas under the receiver operating characteristic curves (ROC) ranging from 0.974 to 0.998.
  • The AUCs were not significantly different between assays (p>0.05).
  • Introduction of multiple result intervals increased the clinical interpretation of all the assays.
  • CONCLUSIONS: Analytical and diagnostic performance of the evaluated faecal calprotectin assays is good, but numerical values differ substantially between the assays necessitating the use of different clinical cut-offs.

MedlinePlus Health Information. consumer health - Breast Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Frequency of oestrogen and progesterone receptor positivity by immunohistochemical analysis in 7016 breast carcinomas: correlation with patient age, assay sensitivity, threshold value, and mammographic screening.
  • AIMS: A routine immunohistochemical (IHC) assay is now commonly used for determining the oestrogen receptor (ER) and progesterone receptor (PR) status of women with breast cancer.
  • To date, no large studies have been conducted that report the expected frequency of receptor positivity in relation to patient age and sensitivity of the IHC assay.
  • METHODS: Members of UK NEQAS-ICC (UK National External Quality Assessment Scheme for Immunocytochemistry) provided data on the receptor status of cases routinely assayed in their departments over a period of two to 26 months between June 1996 and September 1998.
  • Frequency of receptor positivity was correlated with IHC assay sensitivity, the threshold value used to determine receptor positivity, and the presence or absence of mammographic screening in the hospitals or clinics served by the laboratories.
  • There was a significant positive correlation between frequency of receptor positivity and the sensitivity of the IHC assay, for both ER (rs = 0.346; p = 0.019; two tailed) and PR (rs = 0.561; p = 0.003; two tailed).
  • The mean frequency of receptor positivity for laboratories using the same 10% threshold value was 77% for ER (95% confidence interval (CI), 74% to 80%) in laboratories with high sensitivity and 72% (95% CI, 68% to 76%) for those with low assay sensitivity (p = 0.025).
  • For PR, the mean frequency of receptor positivity for laboratories using the same 10% threshold value and having high assay sensitivity was 63% (95% CI, 57% to 69%), and 51% (95% CI, 38% to 65%) for laboratories with assays of low sensitivity (p = 0.022).
  • CONCLUSIONS: Of the parameters investigated, patient age and IHC assay sensitivity were found to be the main variables influencing the frequency of receptor positivity.
  • We recommend the range of receptor values obtained by laboratories achieving high assay sensitivity as a useful guide against which all laboratories can gauge their own results.

9. Jeong TD, Cho EJ, Ko DH, Lee W, Chun S, Kwon HJ, Hong KS, Kim YM, Min WK: A new strategy for calculating the risk of ovarian malignancy algorithm (ROMA). Clin Chem Lab Med; 2017 Jan 20;
NCI CPTAC Assay Portal. NCI CPTAC Assay Portal .

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Reliable quantitative measurements of HE4 and CA125 levels are required to calculate the risk of ovarian malignancy algorithm (ROMA) value.
  • We suggest a new reporting strategy for interpreting ROMA values based on analytical measurement range (AMR) and qualified-intervals of the HE4 and CA125 results.
  • METHODS: HE4 and CA125 assays from Abbott and Roche were used.
  • The AMRs and the qualified-intervals were as follows: Architect HE4 assay, 20-1500 and 17.2-2637.8 pmol/L; Architect CA125 II assay, 1-1000 and 3.9-14,163.0 U/mL; Elecsys HE4 assay, 15-1500 and 28.8-3847 pmol/L; Elecsys CA125 II assay, 0.6-5000 and 6.5-5000 U/mL.
  • These values were used to simulate the ROMA values.
  • RESULTS: Reporting algorithm for the ROMA value could be classified into three categories. (1) If quantitative HE4 and CA125 levels are reliable, the numerical ROMA value can be reported. (2) If HE4 value is <20 and <28.8 for Abbott and Roche in premenopausal woman, the ROMA value should be reported as "low risk" regardless of the CA125 result.
  • In postmenopausal woman, however, it should be reported as "low risk" (CA125<203.0 and <165.8 for Abbott and Roche) or "undetermined" (vice-versa value). (3) If CA125 value is <3.9 and <6.5 for Abbott and Roche, it should be reported as "low risk" (premenopausal HE4<51.5 and <62.2, postmenopausal HE4<323.0 and <281.5 for Abbott and Roche) or "undetermined" (vice-versa value).
  • CONCLUSIONS: New reporting strategy will provide more informative reporting of ROMA values in clinical practice.

  • [Title] Clinical value of M22-based assays for TSH-receptor antibody (TRAb) in the follow-up of antithyroid drug treated Graves' disease: comparison with the second generation human TRAb assay.
  • BACKGROUND: We compared the clinical performances of two new M22-based assays for TSH-receptor antibody (TRAb) with those of the human TRAb assay (hTRAK) in Graves' disease patients at the end of treatment.
  • RESULTS: At T18, the results were significantly higher by the Cobas assay (median: 2.7 IU/L, range: 1.1-18.5 IU/L) or lower by ELISA (median: 0.56 IU/L, range: 0.22-14.8 IU/L) than those obtained for the hTRAK (median: 1.5 IU/L, range: 0.9-9.8 IU/L).
  • CONCLUSIONS: The M22-based TRAb assays did not improve the predictive value of relapse obtained with the hTRAK measured at the end of treatment.
  • High inter-method variability requires assay harmonization for correct interpretation of results.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] The predictive value of clonogenic stem cell assays for the diagnosis of polycythaemia vera.
  • In vitro clonogenic assays can be used to support the diagnosis of PV.
  • However, clonogenic assays are difficult to standardize, and their diagnostic value is accepted as a minor criteria for PV only in the case of positive results.
  • Clonogenic assays need to be validated and normal ranges established carefully before they can be used for diagnostic purposes.
  • In a retrospective study, we analysed the results of 146 consecutive clonogenic assays performed in patients with erythrocytosis between January 1992 and December 2000.
  • The clonogenic assay results were correlated with the final clinical diagnosis of the patients.
  • At a cut-off value of 5 erythroid colony-forming unit colonies per well, 29 out of 38 patients with PV showed positive results, and 9 out of 38 patients showed false-negative results.
  • Thus the positive predictive value of the clonogenic assay for the diagnosis of PV was 97%.
  • We conclude that clonogenic assays, in the case of positive results, and if carefully validated, are very useful and reliable tools for the diagnosis of PV.

  • OBJECTIVE: To determine the value of repeated Clostridium difficile cytotoxicity assays (CA).
  • Assays were grouped into episodes, which were defined as one or more successive tests performed on a single patient within 7 days or less of each other.
  • Of the 947 episodes with two or more CAs, the repeated assays provided new information that was used in patient care in fewer than nine cases.
  • Repeated testing within 7 days of an initial CA accounted for 36% of all assays performed, but provided clinically useful information in only about 1% of cases.

  • [Title] Sperm function assays and their predictive value for fertilization outcome in IVF therapy: a meta-analysis.
  • An objective, outcome-based examination of the validity of the currently available assays was performed based upon the results obtained from 2906 subjects evaluated in 34 prospectively designed, controlled studies.
  • The aim was carried out through a meta-analytical approach that examined the predictive value of four categories of sperm functional assays: computer-aided sperm motion analysis (CASA); induced-acrosome reaction testing; sperm penetration assay (SPA); and sperm-zona pellucida binding assays for IVF outcome.
  • Results demonstrated a high predictive power of the sperm-zona pellucida binding and the induced-acrosome reaction assays for fertilization outcome.
  • On the other hand, the findings indicated a poor clinical value of the SPA as predictor of fertilization and a real need for standardization and further investigation of the potential clinical utility of CASA systems.

  • OBJECTIVE: To explore the value of multiplex ligation-dependent probe amplification (MLPA) for the detection of chromosome abnormalities in miscarriage tissues, and to correlate the result with ultrasound findings.
  • Among the 117 cases with abnormal ultrasound findings, 33 cases (28.21%) had an abnormal MLPA result, 28 out of the 33 cases were numerical chromosome abnormality, 4 cases were chromosome microdeletion and/or micro duplication, 1 case had both numerical abnormality and microduplication.
  • CONCLUSION: Numerical chromosomal abnormalities account for the majority of cases with spontaneous abortion.
  • Combined ultrasound and MLPA assay can improve the detection rate and accuracy for chromosomal abormalities.

  • The authors report the results of more than twelve years' personal research on the value of anti-alphahemolysin (AASTL) and antigammahemolysin (AGSTL) assays for the diagnosis of staphylococcal infections, and particularly of osteoarthritis.
  • These results show that AASTL assay is reliable and often abnormal.
  • However, assay of both hemolysins yields even better results.
  • This dual assay was performed in 57 patients with staphylococcal infection.
  • This represents additional positivity in 15.7% of patients when compared to AASTL assay alone, and in 21% when compared to AGSTL assay alone.
  • The high level of positive results with dual assay is even more striking when only staphylococcal osteoarthritis is considered: one or both hemolysins were increased in 91.1% of these patients (31/34).

  • Alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH) and aspartate aminotransferase (AsT) assays, as well as ultrasonography are the easiest and least expensive examinations to perform in the diagnosis of hepatic metastases.
  • A receiver operating characteristic (ROC) curve was drawn after computing the sensitivity (Se) and specificity (Sp) of each laboratory determination while the threshold indicating that the value was normal was incremented.
  • The examinations were then compared in terms of Se, Sp, positive predictive value and negative predictive value.
  • According to predictive values, laboratory determinations could be classified in decreasing order of usefulness as: AP, LDH, GGT and AsT.
  • Ultrasonography had a positive predictive value of 68 per cent a negative predictive value of 95 per cent, both figures being higher than those of any laboratory examination.
  • These results suggest that ultrasonography has a higher diagnostic value than any of the enzyme assays in the detection of hepatic metastases.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Rapid serological assays for leptospirosis are of limited value in southern Vietnam.
  • In an initial survey, blood samples from 44 patients with undifferentiated fever and 83 healthy subjects were each examined for anti- Leptospira antibodies using three tests: an ELISA; a latex card-agglutination test (Dri Dot); and a lateral-flow assay (LeptoTek Lateral Flow).
  • In the initial survey, although the positive results of the lateral-flow assay, applied to whole blood and serum, showed a good agreement with those of the ELISA (kappa = 0.743), the results of the lateral-flow assay were often indeterminate.
  • When the samples classified as 'indeterminate' in the lateral-flow assay were considered positive, the maximum kappa-value for this assay applied to whole blood was only 0.512.
  • In conclusion, it appears that high seroprevalences of anti- Leptospira IgM and low incidences of acute leptospirosis limit the diagnostic value of the rapid tests that were investigated.
  • The lateral-flow assay is not specific enough.

  • The objective of this study was to evaluate the diagnostic value of ANCA measurement by the indirect immunofluorescence (IIF) test, and by anti-PR3 and anti-MPO ELISA performed in different locations, in patients with idiopathic small vessel vasculitis.
  • Fourteen centers participated in a standardization study of ANCA assays, and entered a total number of 169 newly diagnosed and 189 historical patients with idiopathic systemic vasculitis or iRPGN.
  • The sensitivities of assays in patients were as follows.
  • The specificity of assays (related to disease controls) was: cANCA 95%, pANCA 81%, anti-PR3 87%, anti-MPO 91%.
  • From this study we conclude that the value of the IIF test for ANCA detection can be greatly increased by the addition of a well standardized antigen-specific ELISA.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Technical and diagnostic performance of 6 assays for the measurement of citrullinated protein/peptide antibodies in the diagnosis of rheumatoid arthritis.
  • BACKGROUND: Several anticitrullinated protein/peptide antibodies (ACPA) assays have been reported to be of diagnostic value for rheumatoid arthritis (RA).
  • METHODS: ACPA were determined in 298 serum samples using 6 commercially available ACPA assays.
  • RESULTS: Variable technical performance was noted among the different ACPA assays, with some assays displaying poor reproducibility and bad linearity.
  • ACPA results were well correlated among assays with the same antigen specificity, but the numerical values reported for each assay differed widely.
  • Using cutoff values proposed by the manufacturer, diagnostic sensitivities ranged between 69.6% and 77.5% and specificities between 87.8% and 96.4%.
  • The areas under the ROC curves were comparable among the different assays.
  • CONCLUSIONS: Overall diagnostic performance of ACPA assays is comparable among the different assays, but standardization is needed.
  • For some assays, analytical characteristics could be improved.

  • OBJECTIVES: To assess the prognostic value of hemizona assay (HZA) in predicting the success of IVF.
  • RESULTS: The intra-assay and interassay coefficient of variation were 8% and 14%, respectively.
  • Hemizona assay results had the highest correlation with sperm morphology (r = 0.60).
  • The assay was found to have high sensitivity and specificity rates, at a threshold HZI of 23%.
  • With a threshold HZI of 23%, it has a good predictive value for fertilization rates in IVF, and may thus be used for patient preselection before IVF.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Racial differences in the predictive value of the TDx fetal lung maturity assay.
  • Previous studies have demonstrated a difference in the predictive value of the lecithin/sphingomyelin ratio, a test for lung maturity, between races.
  • Our study examines the predictive value of the newer TDx Fetal Lung Maturity Surfactant-to-Albumin assay.
  • STUDY DESIGN: We reviewed the records of 393 nonblack and 87 black infants delivered within 72 hours of the TDx FLM S/A assay testing.
  • To adjust for possible differences in the timing of lung maturation, the results were stratified by the TDx FLM S/A assay result.
  • This significant racial difference remained when both TDx FLM S/A assay result and gestational age were controlled in a multiple logistic regression analysis.
  • CONCLUSIONS: There are differences in the predictive value of the TDx FLM S/A assay among races.
  • Consideration should be given to a lower cutoff value for a mature test result in black women.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] k-Value-based ferron assay and its application.
  • It has been believed that Al13 could be assayed in term of Al(b) derived from traditional ferron assay.
  • Here, the new k-value-based ferron assay using nonlinear least squares analysis is suggested to resolve the ambiguity.
  • The experimental results reveal that the moderate kinetics (k value) around 0.001 s(-1) can be ascribed to Al13.
  • In the short-term aging of freshly neutralized aluminum solutions with OH/Al molar ratio of 2.2, the rapid progress of Al13-like transformation into Al13 can be traced by this method, whereas it may be masked by traditional ferron assay because the metastable intermediates also contribute absorbance to Al(b) fraction.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Predictive value of the ultrasensitive HIV viral load assay in clinical practice.
  • The aim of this study was to determine whether an HIV viral load of <50 copies/ml (c/ml), in the first available plasma sample to have shown a viral load of <400 c/ml, in patients on antiretroviral therapy, is correlated with longer term suppression of viral load (at <400 c/ml) compared to a viral load of 50-399 c/ml, and secondly, to compare the results obtained by ultrasensitive and standard viral load assays carried out on the same sample.
  • For each patient, the first available specimen showing a viral load of <400 c/ml was tested using the Roche Amplicor ultrasensitive viral load assay, and patients were followed up subsequently for a median period of 52 weeks.
  • Overall, the findings suggest that the advantage in predictive value of the ultrasensitive over the standard HIV viral load assay, shown previously in clinical trials, may be limited in clinical practice.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] The clinical information value of the glycosylated hemoglobin assay.
  • We evaluated the clinical information value of the glycosylated hemoglobin assay by comparing it with practitioners' estimates of glucose control over the preceding 10 weeks in 216 patients with diabetes.
  • Twenty-four per cent of the practitioners' estimates, which were based on historical and laboratory data collected during a routine office visit, differed by more than +/- 75 mg per deciliter from the actual mean blood glucose levels calculated with the glycosylated hemoglobin assay.
  • We conclude that the glycosylated hemoglobin assay provides information about the degree of long-term glucose control that is not otherwise obtainable in the usual clinical setting.

  • OBJECTIVE: The negative predictive value of D-dimer (DD) assay in patients with venous thromboembolic disease is well established for deep vein thrombosis and pulmonary embolism.
  • Little is known about the value of DD assay in patients with superficial thrombophlebitis (ST).
  • The purpose of this study was to assess the value of DD assay in patients with ST of the lower limb.
  • Patients with clinical manifestations suggestive of ST of the lower limbs with positive duplex color Doppler evidence confirming the diagnosis and DD assay results (Vidas D-Dimer Exclusion) within 24 hours were included in the study.
  • DD assay was negative (<500 ng/ml) in 32 patients (32%) and positive in 68 (68%).
  • DD assay was always positive (>or=500 ng/ml) in all patients aged over 70 years (n=22).
  • In patients aged less than 70 years (n=78), DD assay was positive in 46 (59%) and negative in 32 (41%).
  • ROC analysis, sensitivity as a function of specificity by thrombus volume for the entire population, determined the usefulness of a negative DD assay.
  • Considering the critical threshold at 5914 mm(3), sensitivity was 1.0 (95CI 0.89-1.0), with 0.29 specificity (95CI 0.19-0.42), 1.00 negative predictive value and 0.75 positive predictive value.
  • However, the thrombus volume was less than this threshold value in three of the nine cases of ST with extension to the terminal portion of the saphenous.
  • CONCLUSION: A positive DD assay was observed in 68% of patients with ST, with no significant difference with or without varicose veins.

  • [Title] Report on international comparative evaluation of possible value of assays for immune complexes for diagnosis of human breast cancer.
  • There have been several reports on the possible value of measurements of circulating immune complexes for the diagnosis of human breast cancer.
  • Investigators from four laboratories performing assays for immune complexes were sent coded aliquots of serum specimens from the NCI-Mayo Clinic Serum Bank.
  • Although some significant differences in levels of immune complexes between cancer patients and controls were seen, none of the assays had sufficient discriminatory capacity to support optimism about the diagnostic value of this approach.
  • The CEA assay provided significant discrimination between cancer patients and normal donors but did not significantly discriminate between malignant and benign breast diseases.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Diagnostic value of enzyme linked immuno-sorbent assay for cytomegalovirus disease.
  • BACKGROUND: Since interpretation of results of enzyme linked immuno-sorbent assay (ELISA) for diagnosis of Cytomegalovirus (CMV) infection in India is difficult, its diagnostic value required evaluation.
  • AIMS: To evaluate the diagnostic value of ELISA against polymerase chain reaction (PCR) in CMV disease.
  • METHODS AND MATERIAL: Anti-CMV antibodies were assayed by ELISA on the sera of 26 CMV PCR positive and 21 PCR negative patients and 35 normal healthy blood donors.
  • Of the 28 paediatric patients, ELISA was positive in 14 (73.7%) of 19 PCR positive and three (33.3%) of nine PCR negative patients showing a statistically significant difference (Chi square test, P value 0.038).
  • CONCLUSION: ELISA has no diagnostic value in the detection of CMV activation although it may help in the differential diagnosis of CMV infection in the paediatric age group.

  • [Title] The long-term predictive value of the zona-free hamster ova sperm penetration assay.
  • Three hundred sixty-nine infertile couples were followed for 2 to 5 years in a study designed to determine the clinical long-term predictive value of the zona-free hamster ova sperm penetration assay (SPA).
  • Sixteen percent of 131 men who had an SPA of 0%, 23% of 120 men with 1% to 19%, and 48% of 118 men who had a penetration of greater than 19% impregnated their wives 2 to 5 years after the assays.
  • Sperm penetration assay greater than 19% was predictive of higher pregnancy rates in both oligospermic (41% versus 17%) and unexplained infertile couples (52% versus 24%).
  • The specificity and positive predictive values of the SPA were higher than those of the SA (77% versus 57% and 48% versus 37%).
  • These findings emphasize the value and importance of the SPA in determining the long-term fertility potential of men.

  • [Title] Value of different assays for detection of human cytomegalovirus (HCMV) in predicting the development of HCMV disease in human immunodeficiency virus-infected patients.
  • In the present prospective study, five blood tests for detection of human cytomegalovirus (HCMV), nucleic acid sequence-based amplification (NASBA) for detection of early (immediate-early antigen) and late (pp67) mRNA, PCR for detection of HCMV DNA (DNA PCR), culture, and pp65 antigenemia assay, and culture and DNA PCR of urine and throat swab specimens were compared for their abilities to predict the development of disease caused by HCMV (HCMV disease).
  • The pp65 antigenemia assay (sensitivity, 50%; specificity, 89%) and DNA PCR of blood (sensitivity, 69%; specificity, 75%) were most accurate in predicting the development of HCMV disease within the next 12 months.
  • The positive predictive values of all tests however, were low and did not exceed 50%.
  • In conclusion, virological screening by these qualitative assays for detection of HCMV is of limited value for prediction of the development of HCMV disease in HIV-infected patients.

  • [Title] [Clinical diagnostic value of the PCR assay for detection of Mycobacterium tuberculosis].
  • To evaluate the clinical diagnostic value of the PCR assay for detection of M. tuberculosis, a total of 758 samples from 387 patients were assayed by the polymerase chain reaction (PCR) using the IS6110 gene as a target, and the results of the PCR assay were compared with those obtained by conventional culture.
  • The patient's profiles such as clinical situation that required prompt differential diagnosis by the PCR assay, underlying disease and final diagnosis were analyzed.
  • The PCR assay lead to the rapid diagnosis of tuberculosis which was confirmed by culture in all 56 cases including elderly and immunocompromised patients.
  • One hundred and seventy-six of the 231 (76.2%) cases had abnormal shadows in the chest X-ray film that required the PCR assay for diagnosis of tuberculosis and differential diagnosis of pleural effusion, lung cancer or bacterial pneumonia.
  • In 56 smear-negative patients with final diagnosis of pulmonary tuberculosis, the larger the number of specimens received for the PCR assay from each patient, the higher the frequency of positive cases; with 1, 2 and 3 specimens received for the PCR assay, 13.3% (4/30), 45.5% (5/11) and 60.0% (3/5) of cases were PCR positive, respectively.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] The value of synovial fluid assays in the diagnosis of joint disease: a literature survey.
  • OBJECTIVE: To carry out a critical appraisal of the literature in an attempt to assess the current value of synovial fluid (SF) analysis in the diagnosis of joint disease.
  • Firstly, reports assessing the value of the three traditional assays (microbiology, white blood cell counts, and microscopy for pathogenic crystals).
  • Secondly, claims for the usefulness of "new" assays (cytology and biochemical markers).
  • Interpretation difficulties are a major hindrance to the clinical use of biochemical assays, which remain primarily research tools.
  • Finally, work on the diagnostic value of SF analysis in general.
  • The appraisal confirmed that SF analysis remains of major diagnostic value in acute arthritis, where septic arthritis or crystal arthropathy is suspected, and in intercritical gout.
  • Further investigation is recommended into the contribution of SF inspection and white cell counts to diagnosis, as well as of the specificity and sensitivity of SF microbiological assays, crystal identification, and cytology.

  • We assessed the diagnostic value of four commercially available methods for determining pancreatic lipase (LPS) in serum (the turbidimetric procedure from Boehringer, two enzymatic approaches from Kodak and Poli, and an immunochemical assay) in a population of 46 hospitalized patients with acute abdominal pain.
  • Concerning clinical efficiency, all the assays had values equal to or greater than 90%.
  • Using the calculation of the overlap index (OI) as a statistical approach to quantify the clinical utility of various LPS assays, the test having the greatest potential for differentiating between patients with and without acute pancreatitis was the turbidimetric assay (OI = 0.14).

  • METHODS: The additional diagnostic efficacy of the biochemical assays was studied in the ascitic fluid from 130 patients, of whom 57 had peritoneal carcinomatosis.
  • However, increased values were significantly more common in cancer with peritoneal involvement (p < 0.01), giving a sensitivity of 51% and specificity of 97% for carcinomatosis.
  • A cholesterol value exceeding 1.21 mmol/litre was found in 93% of cancers with peritoneal involvement, but it was not entirely specific (96%) for carcinomatosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Determination of dynamic doxorubicin-EC50 value in an automated high-content workstation for cellular assays.
  • To overcome the problems of endpoint tests routinely required for EC50 determination, we utilized a novel automated high-content workstation and calculated a time-resolved EC50 value of MCF-7 mamma carcinoma cells treated with a pharmacologic agent.
  • In particular, the objective was to compare the measuring data of the workstation with a classical standard resazurin cell assay and to transfer the benefit of continuously recorded metabolic data of the workstation to practical time-resolved information about the effect of the applied active reagent (doxorubicin).
  • MCF-7 cells were treated with a broad range of doxorubicin concentrations (100 μM to 1 nM) over 24 h and cellular activities were investigated with both, the resazurin assay and the automated workstation.
  • Twenty-four hours after treatment, the resazurin assay showed an EC50 value (6.3 μM) which was about one decade above the value obtained from oxygen consumption rate (0.37 μM) and extracellular acidification rate (0.72 μM), measured with the workstation.

  • We evaluated urine and peripheral blood mononuclear cell cultures, a qualitative and quantitative antigenemia assay, and a commercially available CMV DNA hybridization assay for their ability to predict CMV disease in 138 HIV-infected patients.
  • The sensitivity, specificity, positive predictive value, negative predictive value, and mean lead times for the antigenemia assay (with use of a threshold of 8 positive cells per 10(5) peripheral blood mononuclear cells as a positive) were 74%, 91%, 63%, 95%, and 95 days, respectively.
  • Corresponding figures for the DNA hybridization assay were 91%, 64%, 34%, 97%, and 152 days.
  • These assays can identify patients at increased risk of CMV disease and should allow a strategy of preemptive therapy to be tested.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] D-dimer concentration increases with age reducing the clinical value of the D-dimer assay in the elderly.
  • BACKGROUND: The D-dimer assay is used as an exclusion test in the assessment of suspected venous thromboembolic disease; patients with a negative result have a low probability of thrombosis.
  • We reviewed the D-dimer results from a hospital and community laboratory using the vidas D-dimer test to assess the influence of age on the D-dimer assay.
  • To test the effect of age on the assay specificity, a cohort of 1897 patients with suspected venous thromboembolic disease was analysed separately.
  • RESULTS: The assay specificity decreased with age from 70% in patients less than 40 years to below 5% in patients more than 80 years.
  • Receiver operator curves were prepared for each age group and the effect of altering the threshold value was analysed.
  • In patients 60-80 years old a threshold value of 1000 ng/mL increased assay specificity to 55% without loss of assay sensitivity.
  • CONCLUSION: The vidas D-dimer assay with a threshold value of 500 ng/mL has little clinical value as an exclusion test in patients more than 80 years old.
  • The assay specificity is poor (26%) in patients aged 60-80 years but could be improved by increasing the threshold value to 1000 ng/mL.

  • [Title] Value of quantitative D-dimer assays in identifying pulmonary embolism: implications from a sequential decision model.
  • OBJECTIVES: To examine the cost-effectiveness of a quantitative D-dimer assay for the evaluation of patients with suspected pulmonary embolism (PE) in an urban emergency department (ED).
  • METHODS: The authors analyzed different diagnostic strategies over pretest risk categories on the basis of Wells criteria by using the performance profile of the ELISA D-dimer assay (over five cutoff values) and imaging strategies used in the ED for PE: compression ultrasound (CUS), ventilation-perfusion (VQ) scan (over three cutoff values), CUS with VQ (over three cutoff values), computed tomography (CT) angiogram (CTA) with pulmonary portion (CTP) and lower-extremity venous portion, and CUS with CTP.
  • CONCLUSIONS: In patients in whom PE is suspected, when CTA is available, even the most sensitive quantitative D-dimer assay is not likely to be cost-effective.
  • When CTA is not available or if its performance is markedly degraded, use of the D-dimer assay has value in combination with CUS and a pulmonary imaging study.

  • [Title] Helicobacter pylori-associated gastroduodenal disease in symptomatic Chilean children: diagnostic value of serological assay.
  • A newly developed enzyme-linked immunosorbent assay (ELISA) IgG serological assay for the diagnosis of Helicobacter pylori infection was used recently in two epidemiological surveys in Chile.
  • To evaluate the diagnostic efficacy of this assay in a local symptomatic pediatric population, we studied 70 school-age patients referred for upper gastrointestinal endoscopy because of complaints suggestive of gastroduodenal disease.
  • This group had significantly higher mean IgG optical density values when compared with the H. pylori-negative group (1.860 versus 0.669; p < 0.001).
  • The sensitivity and specificity of the assay in detecting antral H. pylori were both 90%; the positive predictive value was 98% and the negative, 60%.
  • Accuracy of the assay was superior in predicting the presence or absence of gastroduodenal lesions with a sensitivity of 96%, a specificity of 92%, a positive predictive value of 98%, and a negative predictive value of 86%.
  • We conclude that the diagnostic efficiency of this assay renders it appropriate both to screen for H. pylori-associated gastroduodenal disease in individual patients and to be used in seroepidemiological surveys.

  • [Title] Reducing the standard deviation in multiple-assay experiments where the variation matters but the absolute value does not.
  • When the value of a quantity x for a number of systems (cells, molecules, people, chunks of metal, DNA vectors, so on) is measured and the aim is to replicate the whole set again for different trials or assays, despite the efforts for a near-equal design, scientists might often obtain quite different measurements.
  • This work presents a novel correction method of a very low mathematical and numerical complexity that can reduce the standard deviation of such results and increase their statistical significance.
  • Two conditions are to be met: the inter-system variations of x matter while its absolute value does not, and a similar tendency in the values of x must be present in the different assays (or in other words, the results corresponding to different assays must present a high linear correlation).

  • [Title] [Evaluation of cut-off value for autoantibodies against double-stranded DNA-complexed nucleosomes based on enzyme linked immunosorbent assay].
  • The new classification criteria for systemic lupus erythematosus (SLE) by Systemic Lupus International Collaborating Clinics (SLICC) published in 2012 have defined positive level titer of antibody against double stranded (ds) DNA as more than double the reference range if tested by enzyme linked immunosorbent assay (ELISA).
  • The aim of this study was to evaluate optimal cut-off value and diagnostic performance of the anti-dsDNA nucleosome-complexed (anti-dsDNA-NcX) ELISA, which uses salmon testis DNA complexed with purified nucleosomes as antigens, for diagnosis of SLE.
  • Receiver operating characteristic curve analysis showed that the titer of 44 IU/mL calculated as 99 percentile of 323 healthy volunteers is a better cut-off value for anti-dsDNA-NcX than the 100 IU/mL recommended by the manufacturer.
  • By setting the cut-off value at 44 IU/mL, anti-dsDNA-NcX showed the highest sensitivity (75.0%) and specificity (90.5%) of the 3 assays.
  • In conclusion, anti-dsDNA-NcX has a good diagnostic performance for SLE with our proposed cut-off value of 44 IU/mL.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Value of serum galactomannan assay in the diagnosis of pediatric invasive pulmonary aspergillosis].
  • Many studies suggest that serum galactomannan assay has an excellent sensitivity and specificity for the early diagnosis of adult invasive aspergillosis (IA).
  • However, there have been few studies on serum galactomannan assay in pediatric patients.

  • [Title] Value of pancreatic-type isoamylase assay as an index of pancreatic insufficiency.
  • The study here reported was undertaken to assess the value of assay of the specific isoamylase form arising from the pancreas (P-type) as an index of pancreatic exocrine insufficiency.
  • Abnormally low values for P-type isoamylase in the serum and urine of these patients were infrequent.
  • Conversely, values within the normal ranges for serum P-type isoamylase and Upam/Ucr were common.
  • It is concluded that while subnormal values for P-type isoamylase in the serum and urine may be viewed as supportive evidence for pancreatic insufficiency, failure to find such values does not exclude this condition.

  • [Title] An investigation of the added value of an ACPA multiplex assay in an early rheumatoid arthritis setting.
  • Such assays are designed for exploratory studies.
  • The interpretation of positive antibody reactivities can best be made if the diagnostic and prognostic value of a multiplex array in an early arthritis setting is known and if the multiplex-positive patients who are negative according to three commonly used commercial ACPA assays are characterized.
  • Findings were compared with results primarily of the anti-citrullinated cyclic peptide 2 (anti-CCP-2) assay but also with anti- CCP-3 and anti-mutated citrullinated vimentin (anti-MCV) assays.
  • RESULTS: Thirty-one percent of anti-CCP-2-negative RA patients displayed reactivity toward citrullinated peptides in the multiplex assay.
  • The presence of residual citrulline reactivities detected by this multiplex system in arthritis patients who are negative in commercial ACPA assays needs to be interpreted with caution.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] The value of analytical assays that are stability-indicating.
  • It is essential to validate an assay with regards to its precision, accuracy, reproducibility, selectivity and robustness.
  • In pharmaceutical research, in addition to these requirements, an assay is often required to be proven beyond doubt to be stability-indicating.
  • A stability-indicating assay is one that can accurately and selectively differentiate an intact drug from its potential decomposition products.
  • An assay that fails to meet this requirement would produce stability data that are inaccurate and misleading.
  • In this study, we employed an amperometric HPLC assay developed for the measurements of urinary catecholamines and metanephrines to illustrate the validation process of this assay with regards to its stability-indicating capacity.

  • [Title] Diagnostic value of CA 72-4, carcinoembryonic antigen, CA 15-3, and CA 19-9 assay in pleural fluid. A study of 207 patients.
  • Several tumor markers have been evaluated in pleural fluid, but the value of CA 72-4 assay and of combinations of tumor marker assays has not been firmly established.
  • To find a minimally invasive tool for differentiating between pleural effusions of malignant or benign origin, the authors assessed the diagnostic value of CA 72-4, carcinoembryonic antigen (CEA), CA 15-3, and CA 19-9 assays in pleural fluid individually and in combination.
  • RESULTS: CA 72-4 assay in pleural fluid had an acceptable sensitivity and very good specificity for diagnosing malignant pleural effusion.
  • The combination of CA 72-4 plus CEA plus CA 15-3 yielded the best accuracy, 0.90 (95% confidence interval [CI] 0.85-0.94), with a sensitivity of 0.78 (95% CI, 0.67-0.88), specificity of 0.95 (95% CI, 0.90-0.98), positive predictive value of 0.88 (95% CI, 0.77-0.95), and negative predictive value of 0.91 (range, 0.85-0.94).
  • A good clinical strategy may be to begin with a CEA assay (specificity of I) and then, if it is negative, to add CA 15-3 or even CA 72-4 assays to improve sensitivity.
  • CONCLUSIONS: Assays of CEA, CA 72-4, and CA 15-3 in pleural fluid, or the combination of CEA with CA 15-3 and CA 72-4, was useful in differentiating between pleural effusion of malignant and benign origin.

  • A moderate diagnostic value of enzyme-linked immunosorbent assay is established under screening for tuberculosis of lungs in HIV-negative patients.
  • In view of many positive results in detection of anti-tuberculosis antibodies in control group of patients with HIV-infection the data testified the low diagnostic significance of enzyme-linked immunosorbent assay in group of patients with HIV-infection.
  • The drawbacks of enzyme-linked immunosorbent assay technique of diagnostic of tuberculosis of lungs in common group of HIV-infected patients partially compensated by possibility of its application at late stages of development of HIV-infection.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Predictive Value of the Rapid Whole Blood Agglutination D-Dimer Assay (AGEN SimpliRED) in Community Outpatients with Suspected Deep Venous Thrombosis.
  • CONTEXT: D-dimer assay has been used to screen patients with deep venous thrombosis (DVT).
  • Because both the predictive value and sensitivity/specificity of the test vary according to the type of assay, prevalence, and pretest probability of DVT, clinicians must know the local performance of the d-dimer assay.
  • OBJECTIVE: To evaluate the predictive value of the rapid whole blood agglutination d-dimer Assay (AGEN SimpliRED) in community outpatients with suspected DVT in the Kaiser Permanente (KP) Mid-Atlantic Region.
  • A total of 551 electronic medical records were reviewed, and results of d-dimer assay and compression ultrasonography were tabulated.
  • A total of 129 (23.8%) patients had positive d-dimer; the positive predictive value was 20.2% (CI, 13.2% to 27%).
  • A total of 412 (76.1%) patients had negative test results; three of these patients had DVT shown by compression ultra-sonography; negative predictive value was 99.3% (CI, 98.4% to 100%).
  • CONCLUSION: In the outpatient setting, the rapid whole blood agglutination d-dimer assay (AGEN SimpliRED) used in combination with both clinical judgment and compression ultrasonography exhibited a high negative predictive value comparable with previously reported values.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Predictive value of tube leukocyte adherence inhibition (LAI) assay for breast, colorectal, stomach and pancreatic cancer.
  • The tube LAI assay measures accurately antitumor immunity in patients with early cancer but fails to detect up to 75% of patients with advanced cancer due to excess circulating organ-specific neoantigen (OSN).
  • Substances such as prostaglandin E2 (PGE2) or aminophylline, which increase intracellular nucleotides in leukocytes of patients with advanced cancer reversed this nonreactivity and greatly increased the sensitivity of the assay without any loss of specificity.
  • Antitumor immunity can now be detected in advanced cancer, and a combination of the two assays gives prognostic potential to the assay: a positive test with PGE2 and negative test without indicates the patient has a large tumor burden.
  • The specificity of the assay for each cancer was high and in most instances was greater than or equal to 95%.
  • The PGE2 stimulated assay retained the high specificity.
  • The sensitivity of the regular tube assay was often low, 33-56% because of the many advanced cancer patients tested, whereas the PGE2 stimulated assay showed almost a two-fold increase in sensitivity, 67-93%.
  • The diagnostic value of the assay was estimated by calculating the predictive value for different prevalences of cancer.
  • It was found that at low prevalences of cancer as found in the general population, the assay had a low diagnostic value since few patients with a positive test would have the cancer tested for.
  • With prevalences of cancer of 5% or greater as might be found in a tertiary care clinical setting, the assay would seem to have diagnostic value since one half or more patients with a positive test would have the cancer tested for.
  • Most false positives, but not all, are found in patients who have lesions that are often considered to increase their risk for cancer: severe dysplasia of the breast, colon adenomas, chronic atrophic gastritis and chronic pancreatitis, suggesting that the assay predicts oncogenesis.

  • [Title] Confirmation of positive results for chlamydial antigen by the Chlamydiazyme assay: value of repeated testing and a blocking antibody assay.
  • The distribution of A492 values obtained with specimens which did not repeat as positive was nonrandom and was concentrated between the cutoff values and 0.400.
  • The positive predictive value of the Chlamydiazyme assay after initial testing was 86.7% (396 of 457), but the positive predictive value increased to 94.7% (396 of 418) if specimens which were not repeatedly positive were considered negative.
  • We recommend routinely repeating the Chlamydiazyme assay for all specimens which give A492 values between the cutoff and 0.400 to eliminate many false-positive results.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Primary hyperparathyroidism: value of "intact parathormone" assay (PTH 1-84)].
  • In a prospective study of 20 patients with primary hyperparathyroidism the diagnostic value of the intact parathormone assay was compared with that of intermediate fragment measurement and that of nephrogenic cyclic AMP determination.
  • In addition, the intact parathormone assay enables a thorough study of the relationship between ionized calcaemia and parathyroid secretion to be performed and confirms the existence, in hyperparathyroid patients, of two types of secretory response to a rise in calcaemia.
  • Being more reliable than the measurement of a C-terminal or intermediate fragment and easier to perform than nephrogenic cyclic AMP determination, the intact parathormone assay seems to be particularly suitable for the study of primary hyperparathyroidism.
