A member asked:
Does a 4th generation hiv test detect even the rare strains of the virus if after the window period for the tests are negative?
A doctor has provided 1 answer
Yes. The antigen component of the test doesn't detect HIV2, but the antibody test does. Other HIV1 variants always give positive AgAb (4th generation) test results.

Just asking in curiosity. Do all LAB 4th Gen HIV negative tests need to be confirmed by a second test, even if the first test is done outside the window period? Or is one HIV test outside of 6 weeks enough?
