Human Immunodeficiency Virus 1, Antiretroviral Drug Resistance Testing - HIV Drug Resistance

Immediate treatment with antiretroviral therapy (ART) is recommended for all individuals with a diagnosis of human immunodeficiency virus (HIV). Many different drugs and multidrug regimens may be used successfully to suppress viral replication (see U.S. Department of Health and Human Services Guidelines for the Use of Antiretroviral Agents in HIV-1-Infected Adults and Adolescents). However, resistance can develop to any drug class or regimen.   Drug resistance testing is recommended before the start of therapy to guide selection of treatment regimens and should be performed for treatment guidance when treatment failures occur.  Drug resistance variants can be detected using phenotypic and genotypic methods, but genotypic methods are preferred in most circumstances.  See Drug Resistance Testing below.
