If HIV infection is diagnosed, genotypic testing of the infecting strains for antiretroviral drug resistance is recommended. [7] Resistance testing at baseline will be helpful in guiding the selection of an antiretroviral drug regimen that can provide the optimal virologic response. See Antiretroviral Therapy for HIV Infection. Genotypic testing is recommended whether antiretroviral therapy will be given for acute infection or will be deferred until the CD4 count declines below threshold levels.
