Analytical Performances of Human Immunodeficiency Virus Type 1 RNA-Based Amplix® Real-Time PCR Platform for HIV-1 RNA Quantification

Figure 5

Mean differences (log copies/mL) of HIV-1 RNA loads measured in parallel by HIV-1 RNA-based Amplix real-time PCR assay (Biosynex) and by the reference COBAS AmpliPrep/COBAS TaqMan HIV-1 test v2.0 (Roche Molecular Diagnostics) in clinical plasma samples from 168 patients receiving antiretroviral regimen and in virological failure, representing a broad series of HIV-1 group M B subtype and non-B subtypes. Significant differences between two paired HIV-1 RNA load results were taken above 0.5 log.
