HIV antiretroviral drug resistance testing should be performed prior to initiating antiretroviral therapy (ART) and should be performed if the woman is receiving ART with virologic failure (defined as an HIV viral load >200 copies/mL but may be unsuccessful with an HIV viral load from 200-1000 copies/mL).

If a woman with HIV infection presents late in pregnancy, ART should be initiated immediately, before availability of resistance testing.
