2. What is HIV phenotypic resistance testing?
HIV phenotypic resistance testing is the same as genotypic testing in that it tests the strain of
HIV causing your infection for resistance to specific ARV but uses a different method. In the lab, a sample of the virus grown in
culture is mixed with different concentrations of one or more drugs. If the virus is able to replicate in the presence of the drug, as compared to a known strain of virus (a reference virus), it is said to be resistant to that drug. This type of testing usually takes longer than genotypic resistance testing.
