Laboratory Assays in the Clinical Management of Antiretroviral Therapy
Summary
- One phenotypic tropism assay using plasma virus is available
- Results are reported as R5, X4, or R5/X4 (dual/mixed)
- Enhanced sensitivity version of this assay in current use can detect X4-tropic virus nearly 100% of the time when X4 virus is present at 0.3% of the total viral population[Trinh 2008; Su 2008; Reeves 2007]
- Results are reported as R5, X4, or R5/X4 (dual/mixed)
