The prevalence of HIV resistance has been increasing from the usage of AZT. Studies in US indicated that the prevalence was approximately 50% in patients who had experienced antiretroviral therapy.2 Antiviral regimens based on resistance tests could efficiently decrease viral load, increase CD4 cell counts and significantly improve the efficacy of antiretroviral therapy.3 There are two methods commonly used to test HIV resistance at present： one is genotypic resistance assay which predict HIV resistance based on resistance mutations in the viral genome; the other is a phenotypic resistance assay which directly evaluates HIV resistance through analyzing drug sensitivity in vitro.展开更多
