Comparison of versions 1.0 AND 1.5 of the UltraSensitive AMPLICOR HIV-1 MONITOR test for subjects with low viral load

J Brooks Jackson et al. J Clin Microbiol. 2004 Jun.

Abstract

We compared the performance of two UltraSensitive AMPLICOR HIV-1 MONITOR kits (version 1.5 [v1.5] versus v1.0) by retesting 404 plasma samples with low viral loads (<3,000 copies/ml) with both kits. With 292 samples that initially had <50 copies/ml by the v1.0 kit, the v1.5 assay was more sensitive than the v1.0 assay for samples with human immunodeficiency virus type 1 RNA near the 50-copy/ml cutoff (P = 0.0146). Median numbers of copies per milliliter were similar for 112 samples with 50 to 3,000 copies/ml with no difference in sensitivity with a 200-copy/ml cutoff.
