Evaluation of real-time PCR laboratory-developed tests using analyte-specific reagents for cytomegalovirus quantification.
Viral load testing for cytomegalovirus (CMV) has become the standard for the diagnosis of infection and monitoring of therapy at many transplant centers. However, no viral load test has been approved by the FDA. Therefore, many laboratories rely on laboratory-developed assays. This study evaluated the performance characteristics of two real-time PCR tests developed using the artus CMV analyte-s...
متن کاملQuantification of human cytomegalovirus DNA by real-time PCR.
A quantitative real-time PCR assay was developed to measure human cytomegalovirus (HCMV) DNA load in peripheral blood leukocytes (PBLs). The HCMV DNA load in PBLs was normalized by means of the quantification of a cellular gene (albumin). The results of the real-time PCR assay correlated with those of the HCMV pp65-antigenemia assay (P < 0.0001).
متن کاملEvaluation of new commercial real-time PCR quantification assay for prenatal diagnosis of cytomegalovirus congenital infection.
A new commercial real-time human cytomegalovirus (HCMV) PCR kit was evaluated after automated DNA extraction of 153 amniotic fluids in parallel with an in-house real-time PCR assay. The commercial kit displayed 100% sensitivity/specificity compared to the "in-house" assay and was suitable for prenatal diagnosis of HCMV congenital infection.
متن کاملMultilaboratory evaluation of real-time PCR tests for hepatitis B virus DNA quantification.
The performance characteristics of four different assays for hepatitis B virus (HBV) quantification were assessed: the Abbott RealTime HBV IUO, the Roche Cobas AmpliPrep/Cobas TaqMan HBV test, the Roche Cobas TaqMan HBV test with HighPure system, and the Qiagen artus HBV TM ASR. Limit of detection (LOD), linear range, reproducibility, and agreement were determined using a serially diluted plasm...
متن کاملQuantification and Optimization of Candida albicans DNA in Blood Samples Using Real- Time PCR
Background: Candida albicans (C. albicans) is a major cause of candidaemia in people with impaired immunity. Blood culture is a “gold standard” for candidaemia detection but is time-consuming and relatively insensitive. We established a real-time PCR assay for C. albicans detection in blood by LightCycler PCR and melting curve analysis. Methods: Five milliliter blood samples from...
