I would really appreciate an explanation of the following. 1. Can viral load tests detect all genotypes of HIV I. What about HIV II [over 50 copies]? 2. Does everyone who tests HIV+ show a detectable viral load[ assuming that they are not taking any meds ]? 3. Why would a PCR test not detect HIV if it were present ?Would there be any other reason apart from the fact that it was below the detectable range ?
Response from Dr. Holodniy
1. Most available viral load assays can detect clinically relevant and wide spread strains. HIV-1 viral load assays cannot detect HIV-2. 2. As far as I know.
3. If it were a strain with a genetic sequence that the assay could not detect.
