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.
-
Consulting Healthcare Professionals
- Discuss results and timing with a healthcare provider for personalized advice.
- They can guide you on next steps based on your risk factors and test outcomes.

View allI'm really worried about my brother who's had a fever for about a week now. The fever comes and goes and our family doctor suggested a Widal test. His results came back with S. typhi O 180, S. Typhi H 180, S. Paratyphi AH 120, and S. Paratyphi BH 120. I'm not sure what these numbers mean. Could you tell me if it looks like he has typhoid?
report it normal but it will not exclude the possibility by 100% because there may be false negative , consult physician and show the report

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 concerned about my situation here. I was bitten by a street cat before and went through the full rabies vaccination series of 5 doses. Then, 6 months later, the same cat bit me again, and I got 3 more doses of the vaccine. Now, if this same cat bites me once more just 2 months after my last rabies shot, do I need to get vaccinated again? If so, how many doses would be necessary? Also, just to mention, the cat hasn't been vaccinated. What should I do?
After two previous bite incidents and vaccination series, if bitten again by the same unvaccinated cat, you'll likely need a booster dose. Here's a general guideline: Consult a Doctor Immediately 1. Report the incident and previous vaccination history. 2. Discuss the need for a booster dose. General Recommendations 1. If the previous vaccination series was completed (5 doses), a booster dose of 1-2 injections might be sufficient. 2. If the incident occurs within 2 months of the last vaccination dose, a booster dose might not be necessary.
