A member asked:
In regard to 4th gen ab/ag hiv testing, if you had no immune response at 81 days (ie no antibodies detected) wouldn't p24 protein still be detectable in that case?

If test is done early, p24 antigen can be positive but antibody test may still be negative at that time; however, by 81 days the antibody test should be positive if p24 antigen is positive or if antibody is negative, p24 antigen should also be negative.

To be sure, get a HIV nucleic acid test at 6 months after exposure.
