From: HIV-1 low-level viraemia assessed with 3 commercial real-time PCR assays show high variability
Repeatability of VL below 50 cop/ml in clinical settings. A. Inter-assay variability. The plasma VL of sixty-one samples were tested with the assays from Siemens=Versant HIV-1 RNA 1.0 kPCR (Siemens), Abbott=Realtime HIV-1 (Abbott), Roche=Cobas Ampliprep/Cobas Taqman HIV-1 v2.0 (Roche). B. Intra-assay repeatability on 40 triplicates tested with Versant HIV-1 RNA 1.0 kPCR (Siemens). C. Intra-assay repeatability on 40 triplicates tested with Realtime HIV-1 (Abbott). D. Intra-assay repeatability on 40 triplicates tested with Cobas Ampliprep/Cobas Taqman HIV-1 v2.0 (Roche).
