Comparative evaluation of the automated Roche TaqMan real-time quantitative human immunodeficiency virus type 1 RNA PCR assay and the Roche AMPLICOR Version 1.5 conventional PCR assay.

Abstract:

:The need to evaluate antiviral treatment response and the emergence of resistance have made the human immunodeficiency virus (HIV) viral load assay a major feature of the diagnostic monitoring of HIV-infected individuals. The objective of this study was to evaluate the utility of the recently In Vitro Diagnostic Medical Devices Directive-approved Roche COBAS AmpliPrep/TaqMan96 real-time PCR assay by comparison with the existing Roche COBAS AmpliPrep/AMPLICOR MONITOR conventional PCR assay. EDTA-treated plasma samples from 191 HIV-1-infected individuals were tested for HIV-1 RNA by the AMPLICOR assay and the TaqMan assay. This was a prospective study using 191 pairs of samples from the same bleed per patient. The correlation coefficient of the assays was 98.08%. The mean difference between the assays was 0.05 log(10) copy/ml plasma, with a standard deviation (SD) of 0.27 log(10) copy/ml plasma. Thirteen samples gave results with variances greater than 0.5 log(10) copy/ml plasma, which is our clinical cutoff. Two samples were more than 3 SD different (0.81 log(10) copy/ml plasma). The TaqMan assay appeared to be slightly more sensitive at the lower end of the dynamic range. The assays correlated significantly (P > 0.95) with each other, and the regression analysis was also highly significant (R(2) > 0.95).
