Abstract

ABSTRACT New commercial techniques for determination of the viral load (VL) in plasma are able to detect as few as 20 copies of HIV-1 RNA/ml. The relevance of this new technical threshold is uncertain. Upon multivariate analysis, factors associated with detection of VLs between 20 and 49 copies/ml by the Cobas TaqMan HIV-1 v2.0 assay in an HIV clinic were the basal VL and time on antiretroviral therapy.
