Q: does hiv 4th generation test detect antibodies for both hiv 1 & 2 or it detect antigens for hiv 1 and detect antibody for hiv 2 ?

: The AgAb (4th generation) HIV blood tests detect both antigen and antibody for HIV 1, but only antibody for HIV2. If your test is negative more than 6-8 weeks after your last possible exposure, you can be sure you have neither virus.
