A member asked:
Hi dr. would a 4th gen hiv test (clia) be positive at d30 for someone infected with hiv and co-infected with cmv/hcv? since seroconversion is delayed, would p24 antigen be detected at day 30 post exposure? thanks?
A doctor has provided 1 answer
There are no medical conditions or drugs known to delay positive results of the HIV antigen-antibody (4th generation) blood tests, including CMV or HCV. The reported association with HCV is not conclusive; if valid, it only affects HIV antibody, not p24 antigen and therefore not the AgAb blood tests. A negative HIV AgAb test is always 98-99% reliable at 30 days (100% at 6 or more weeks).
