Doc, is it still possible to test positive after testing negative 1 year from the possible exposure? I was informed that it could take up that it could take up to 18 months to be fully accurate. Is that true doc? I'm really worried. Please, I need your advised.

No, most tests are positive by 3 months, we add a 6 month test for the few late converters that may possible. Even if a person took post-exposure meds (PEP) they would be expected to be positive by 6 months. Of course a person coould always become popsitive later if they have ongoing risky behavior and that is a reason to retest in that setting. Some of our new tests combine antigen and antibody screens and can test positive as early as 2 weeks after infection. These tests should help to eliminate much of this unecessary anxiety.
