BACKGROUND Viral load (VL) monitoring is the standard of care in developing country settings for detecting HIV treatment failure. Since 2010 the World Health Organization has recommended a phase-in approach to VL monitoring in resource-limited settings. We conducted a systematic review of the accuracy and precision of HIV VL technologies for treatment monitoring. METHODS AND FINDINGS A search...
AIMS To evaluate the sensitivity of the Roche Cobas, Roche Amplicor plate kit, ligase chain reaction (LCR), and an in house polymerase chain reaction (PCR) by titration of purified elementary bodies (EB) and also to test 245 urethral and endocervical specimens for Chlamydia trachomatis by the four assays as well as conventional culture. STUDY DESIGN EB titrations were run in duplicate in each...
A post hoc analysis of the ATHENA study was performed to determine whether true HPV-negative cervical lesions occur and whether they have clinical relevance. The ATHENA database was searched for all CIN2 or worse (CIN2+) cases with cobas HPV-negative results and comparison was made with Linear Array (LA) and Amplicor to detect true false-negative HPV results. Immunostaining with p16 was perform...
In this study, we established a fully automated molecular assay for qualitative detection of hepatitis C virus (HCV) in serum and whole-blood samples and compared it with conventional molecular assays, including manual HCV RNA extraction protocols. Whole-blood samples were collected from patients with and without chronic HCV infection in EDTA tubes and nucleic acid stabilization tubes (NASTs). ...
BACKGROUND We examined the detection of low-level viraemia at week 24 as a predictor of sustained virological response (SVR) and viral relapse/breakthrough, and the agreement between the Roche Cobas TaqMan™ HCV RNA assay (TaqMan) and Roche Cobas(®) Amplicor HCV qualitative assay (Amplicor; both Roche Molecular Diagnostics, Pleasanton, CA, USA) for detection of low-level viraemia. METHODS A to...
Cobas Amplicor CMV Monitor (CMM) and Quantiplex CMV bDNA 2.0 (CMV bDNA 2.0), two new standardized and quantitative assays for the detection of cytomegalovirus (CMV) DNA in plasma and peripheral blood leukocytes (PBLs), respectively, were compared to the CMV viremia assay, pp65 antigenemia assay, and the Amplicor CMV test (P-AMP). The CMV loads were measured in 384 samples from 58 human immunode...
