Test ID: HIRGT    
HIV-1 RNA Quantification with Reflex to HIV-1 Genotypic Drug Resistance to Protease and Reverse Transcriptase Inhibitors, Plasma

Useful For Suggests clinical disorders or settings where the test may be helpful

Quantifying plasma HIV-1 RNA levels (viral load) in individuals living with HIV, including children, followed by identification of genotypic mutations associated with viral resistance to inhibitors of HIV-1 reverse transcriptase and protease


Guiding initiation or change of combination antiretroviral therapy in individuals, including children, living with HIV

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If HIV-1 RNA level is 500 copies/mL or higher, then HIV-1 genotypic drug resistance mutation testing will be performed at an additional charge.
