I'm trying to understand the window period for the HIV 1 and 2 antibodies and p24 antigen test, like the CMIA test. Is it safe to say that getting tested three months after exposure would give me a conclusive result? I've been stressing about it and just want to make sure I'm doing the right thing. Can you shed some light on this?

The window period for HIV 1 & 2 antibodies and p24 antigen test using CMIA method is typically around 4 weeks to 3 months after exposure. For most individuals, this test is considered conclusive after 3 months post-exposure. It is important to follow up with your healthcare provider for further guidance and monitoring.

I'm really worried about my HIV status. I had unprotected sex about a year ago and did a screening test for HIV 1 and 2 antibodies, which came back non-reactive at 0.1. I recently took the HIV 1, 2, and p24 combo test again and got the same non-reactive 0.1 result. Should I be concerned, or can I trust these results?

can you clarify your concern i am unable to understand your concerns
