Hey, I'm a bit worried and need some advice. I took an HIV 1 and 2 ECLIA antibody test on the 63rd day after potential exposure, and it was done using the Roche e411 analyzer. I'm curious about how accurate the results might be at this stage. Should I trust the results, or do I need to retest later?

At 63 days post-exposure, an HIV 1 and 2 ECLIA antibody test using the Roche e411 analyzer is highly reliable. This test detects antibodies and possibly antigens related to HIV, and by this time frame, most individuals who have contracted HIV will test positive. However, no test is 100% definitive immediately after exposure.
-
Accuracy at 63 days: The test is considered very accurate, with a high sensitivity and specificity, meaning false negatives are rare at this stage.
-
Trusting the results: If your test is negative, it is very reassuring, but some guidelines recommend a follow-up test at 3 months (90 days) post-exposure for complete confirmation.
-
Retesting: If your initial test is negative and you have no ongoing risk, a retest at 90 days can provide additional reassurance. If positive, confirmatory testing will be done by your healthcare provider.
-
Next steps: Discuss your results with a healthcare professional who can guide you on any further testing or preventive measures.
Overall, your test at 63 days is a strong indicator of your HIV status, but a follow-up test at 90 days is often advised for absolute certainty.

Hey, I've got a question about the P24 antigen antibody test. If I take it a month after possible exposure, will the results be conclusive for HIV, or should I consider getting another type of test too? I'm anxious to know how accurate it really is at that point.
The P24 antigen-antibody duo test is highly accurate when done after one month of potential exposure, as it detects both the HIV virus and antibodies. However, for a conclusive result, it's recommended to confirm with a follow-up test, such as the HIV RNA PCR test or another antibody test, at 3 months post-exposure.

I'm really worried because I had unprotected oral sex with a commercial sex worker back in October 2020. Since then, Ive had persistent lymphadenopathy. I've taken numerous tests: HIV Tridot on December 6th came back negative, HIV ELISA on December 16th also negative. I had an HIV-1 RNA PCR test in the first week of January which was negative, and then HIV-2 RNA PCR and western blot on January 19th also negative. Even tests like the HIV duo on January 30th and western blot on February 10th were negative, and I did assessments at the 7-month mark including HIV duo, western blot, HIV qualitative RNA PCR, and ICTCall came back negative. Should I still be worried about HIV?
