A member asked:
Can p24 components of hiv 4th generation test cross react with hiv2 or it is specifically for hiv1?
A doctor has provided 1 answer
4th gen HIV test: The p24 component of the 4th generation HIV tests is only for HIV1. I'm not aware of any cross reaction on it. The antibody component includes HIV2, however.
