DNA Sequencing • Reverse Transcriptase Polymerase Chain Reaction (RT-PCR)
An infection is often composed of a variety of strains of the virus. The test may identify only the predominant type of virus thus leaving the minority viruses to thrive once the predominant type is treated. Lack of resistance may not confer susceptibilities.
See Laboratory Report
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.
