Hi, I had unprotected sex with my partner whom I don’t know his status. So we decided to test, the first test using a test kit from unknown manufacturer showed a faint line and a dark control line. I bought Bio Sure after a week to confirm the results and it came out negative. So my question is, if a person is on ARV’s can he test HIV negative? I saw the package written “not recommended for a person on ARV”. Just curious, and can I over rule the first test with the second one?
