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.

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 feeling really anxious because a while back, I had a risky encounter with someone whose HIV status I don't know. It's been 180 days since then, and I did an HIV test on day 179. The test I took was the HIV 1 and 2 p24 CMIA, and the result came back negative with an index value of 0.09. I'm trying to understand more about the window period for HIV testing and whether the CMIA test is as reliable as the ELISA test. Also, does taking the test two days earlier, like on day 179, affect the accuracy at all? I had multiple tests throughout this periodone at three months with an index of 0.07 and another at day 42, which was also negative with the same index value. Can you help me make sense of all this?
Advised elisa hiv test at 6 months and at 1 year.

I'm just curious about how reliable the HIV rapid test is at the six-month mark, like after 180 days. Can you share if it's considered conclusive by then?
No it's not confirmatory, it's screening test, confirmatory test would be ELISA.

I recently found out that my girlfriend had a past relationship, and now I'm just a bit anxious about things. To be cautious, I decided to get tested for HIV 1 and 2 using the Elisa method, and my results came back with a value of 0.09. I've attached my test report here. Could you help me understand what this means? Should I be worried or take any further steps?
-Hello, It's understandable that you're concerned. A result of 0.09 from the HIV 1 and 2 ELISA test is typically considered negative, as it is well below the cutoff for positivity. However, it's always a good idea to follow up with a healthcare profes
