Clinical Use

This test is intended for use in conjunction with clinical presentation and other laboratory markers of disease progress for the clinical management of HIV-1 infected patients. The test identifies drug resistance-associated mutations in the HIV-1 protease and reverse transcriptase genes. It can be used to predict antiretroviral drug resistance before initiation of therapy and in patients experiencing virologic failure while on therapy.
