Q: 4th gen test on hiv works on all types and subtypes of hiv ?and if somebody cant create antibody antigen p24 is always there ?

: Yes, the test detects all HIV types and subtypes. And yes, if for some reason antibody doesn't develop, p24 antigen will remain detectable. Don't over think it: if you have had a negative AgAb (4th generation) HIV blood test more than 6 weeks after the last possible exposure, it is 100% certain you did not catch HIV. There are no exceptions.

Hi Dr. CMV/HCV co-infection with HIV delays seroconversion. How common is this? Would 4th Gen HIV test detect P24 antigen in this case, at Day 30 post exposure even if there is a delayed antibody response? Thanks?
