Test Includes: Reflex to genotype (at additional charge) if viral load is >500 copies/mL Use: Detect and quantitate HIV-1 in plasma with reflex to genotype (at additional charge) if viral load is >500 copies/mL. GenoSure® MG test detects mutations in the HIV viral genes that encode the HIV protease and polymerase (reverse transcriptase). Mutations in these genes have been associated with resistance to antiretroviral drugs. Limitations: Assay range: 20?10,000,000 copies/mL Methodology: Cobas® AmpliPrep/Cobas® TaqMan® HIV-1 Test, Version 2.0 Synonyms: HIV-1 RNA by Real-time PCR, Quantitative Reflex to Genotype Viral Load.
