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.
Answered by 1 Apollo Doctors
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.

Understanding the P24 Antigen Antibody Test
- The P24 antigen antibody test detects HIV antigens and antibodies, indicating early infection.
- It differs from other tests by identifying the virus sooner than antibody-only tests.
-
Timing and Accuracy of the Test at One Month Post-Exposure
- The P24 test is typically accurate from 2-4 weeks post-exposure.
- At one month, it is generally reliable, but not definitive for all cases.
-
Recommendations for Additional Testing
- Follow-up testing is advised to confirm results.
- Consider a nucleic acid test (NAT) or a fourth-generation test for comprehensive results.

View allI'm really worried right now. I had sex with a sex worker and used a condom, but I'm anxious about the risks of HIV. Is there any chance of getting HIV if the outside of the condom touched my penis after ejaculation? Also, after I touched her vagina and then my penis, could that have been risky too? Another thing, I kissed her body but avoided her lips and vagina. Should I be concerned about that? Please help me figure out what to do next.

I recently had a risky encounter with a commercial sex worker and was pretty worried about HIV exposure. I went to see a doctor right away and started a post-exposure prophylaxis treatment with tenofoviremtricitabine and raltegravir, just under 12 hours after the exposure. I just finished the 28-day course and got tested on the 29th day with a CMIA test that came back negative. Does this mean Im in the clear, or should I be concerned about anything else related to HIV?
It's reassuring that your CMIA test on Day 29 was negative, and you took PEP promptly, which greatly reduces HIV risk. However, follow-up testing at 6 weeks and 3 months post-exposure is crucial to confirm your status fully. Stay positive and consult your doctor for guidance.

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?
