4 months after an incident would give you certainty.
I do not know why you took a p24, an AB test would be just fine.

If you are infected, a P24 test is unreliable after 4 weeks.

The second half of a Duo test is an antibody test.

Why is a p24 test unreliable at 4 weeks when this is the time period manufacturers state it is most effective at (28 days)?

second to that teak. I got my P24 and A/B test done after 25 days of exposure. What you think about accuracy in that time frame.
