Background: Accurate quantitation of plasma Human immunodeficiency virus-1 (HIV) RNA
levels is required for clinical management of HIV-1-infected patients. Several assays are …

Concordance between molecular assays may be suboptimal at low HIV-1 viremia levels (<
1,000 copies/ml); therefore, it may be difficult to define and compare virologic endpoints for …

Significant underquantitation of HIV RNA has been reported with the Roche Cobas
AmpliPrep/Cobas TaqMan HIV Test (Version 1) compared to other assays. However, these …

The large underestimations of HIV RNA quantification observed in 17 patients with the first
version of Cobas TaqMan assay have been successfully corrected in the upgraded version …

BACKGROUND: HIV-1 RNA is a key parameter for reliable diagnosis and treatment of HIV-1
infection. The determination of HIV-1 RNA reduces the pre-seroconversion period in the …

The COBAS AmpliPrep/COBAS AMPLICOR HIV-1 MONITOR Test, version 1.5 (CAP/CA),
and the COBAS AMPLICOR HIV-1 MONITOR Test, version 1.5, were compared. CAP/CA …

ABSTRACT The Abbott RealTime human immunodeficiency virus type 1 (HIV-1) assay
(ART) and the Cobas AmpliPrep/Cobas TaqMan HIV-1 test (CTM) are commercially …

Background Viral load quantification is standard for monitoring HIV-1 therapy and is crucial
in deciding whether to switch or to continue a current antiretroviral regimen. In Japan, serum …

Background Plasma HIV-1 RNA levels (pVLs), routinely used for clinical management, are
influenced by measurement error (ME) due to physiologic and assay variation. Objective To …

Abstract Background. The COBAS AMPLICOR HIV-1 MONITOR Test, version 1.5 (Amplicor)
has been replaced with the COBAS AmpliPrep/COBAS TaqMan HIV-1 Test, version 2.0 …
