Question

I took an HIV 1 and 2 antibodies screening and an HIV 1 and 2 p24 combo test 86 days after I was exposed. The results came back negative. Can I be sure that's conclusive at this point?

A negative HIV 1&2 antibodies and p24 combo test after 86 days (approximately 3 months) of exposure is highly suggestive of non-infection, but not conclusive. Here's why: Reasons for Caution 1. Window period: HIV antibodies may take up to 3-4 months to develop. 2. False negatives: Rare, but possible due to laboratory errors or test sensitivity. 3. Viral load: Low viral load may not trigger antibody production. Next Steps 1. Repeat testing: Schedule another HIV test 3-6 months after initial exposure.

I'm really worried because my father-in-law just tested positive for COVID-19. His report says "RESULTS Positive" but there's also something called "Bio Ref Interval" that shows as "Negative." Can you help me understand what that means? Is this related to a stage of COVID-19, or does it indicate something else?
