A member asked:
Is there any chance my 4th generation hiv test could be false negative? from 27 days post exposure?
A doctor has provided 1 answer
It takes up to 45 days for the HIV AgAb (4th generation) blood tests to become positive. However, by 27 days 98% of infected persons test positive. Almost certainly you were not infected, but to be certain you need one more test after 45 days.
