was isolated. Based on varying real-time RT- PCR results of additional straws from cut-off samples it is highly recommended to analyse at least five straws per semen batch before declaring semen free of ...
Triage of women with equivocal or low-grade cervical cytology results: a meta-analysis of the HPV test positivity rate.
in HPV positivity between the two triage groups was large and highly significant: 32% (95% CI: 27-38%). HPV rates dropped tremendously as age and cutoffs of test positivity increased. Other factors ...
Pooled analysis of the accuracy of five cervical cancer screening tests assessed in eleven studies in Africa and India.
even at the lowest cutoff of atypical squamous cells of undetermined significance (57%; 95% CI 38-76%) for CIN2 + but the specificity was rather high (93%; 95% CI 89-97%). The HC2-assay showed ...
Evaluation of antibody-ELISA and real-time RT-PCR for the diagnosis and profiling of bluetongue virus serotype 8 during the epidemic in Belgium in 2006.
the cELISA, using RT-qPCR as standard of comparison, showed that the cut-off point with the highest accuracy occurred at a percentage negativity of 66, which is markedly higher than the cut-off proposed ...
Liquid compared with conventional cervical cytology: a systematic review and meta-analysis.
specificity, considering high-grade and low-grade squamous intraepithelial lesions as cutoff, was similar in conventional and liquid cytology. However, a lower pooled specificity was found for liquid-based ...
Uncertainty of measurement for competitive and indirect ELISAs.
transformed into confidence intervals around the corresponding observed values and further transformed into probabilities of being above/below a cut-off. Logistic regression models were subsequently used to ...
Performance of automated measurement of antibodies to cyclic citrullinated peptide in the routine clinical laboratory
were obtained for FEIA and ELISA, respectively. Both methods were concordant in 97% of cases. Increasing the cut-off for the ELISA system from >5 U/mL to >11 U/mL resulted in lower sensitivity ...

Chapter 9: Clinical applications of HPV testing: a summary of meta-analyses.
follow-up cytology. Primary screening with HC2 generally detects 23% (95% confidence interval, CI: 13-23%) more CIN-2, CIN-3, or cancer compared to cytology at cut-off atypical squamous cells of undetermined ...
Detection of HCV antibodies in oral fluid.
a sensitivity and specificity of 83.6% (95% CI: 72.7-90.9%) and 100.0% (95% CI: 93.8-100.0%), respectively. Comparing S/ CO of concordantly positive and negative samples, the cut-off point was lowered by 30% ...
