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.

So, I've been with my wife for two years now, and we got married in May 2015. We started off using condoms, but for the past few months, at least three I think, we've stopped using them. Both of us got tested for HIV and the results were non-reactive, which was done on May 23, 2016. This was after at least three months of having unprotected sex. The test we did is the ECLIA Cobas e411 Roche. Do you think there's any need to redo the HIV test, or is it fine as long as we're both staying loyal to each other? Is the test we have already sufficient?

ideally not needed unless you have concern.get yourself tested once in a year

I'm really worried after visiting a barber shop because I'm afraid I might have been exposed to infections like HBV, HCV, or HIV. Could you tell me more about when I should get tested? I heard that an antibodies test for HIV can be done after 4 weeks or even up to 12 weeks, but I also read something about a p24 antigen test that can be taken after 4 weeks. How accurate are these tests? I could really use some advice right now.

Antibodies test for HIV can be performed after 4 weeks for preliminary results, but for more accurate results, it is recommended to wait for 12 weeks post-exposure. The p24 antigen test can be performed after 4 weeks to detect the HIV virus directly. It is important to follow up with healthcare provider for further evaluation and management.
