Testing for HIV at 35 days is a good start, but it's essential to understand that the reliability of the result depends on the type of HIV test used and the testing window period.
There are different types of HIV tests, and their reliability varies depending on the timing of the test after potential exposure to the virus. The two main categories of HIV tests are:
Antigen-antibody tests (4th generation tests): These tests look for both HIV antibodies and the p24 antigen, which is a viral protein. They can detect HIV infection earlier than antibody-only tests, typically within 2 to 6 weeks after exposure. The window period for these tests is around 2-4 weeks.
Antibody tests (3rd generation tests): These tests only detect HIV antibodies and have a longer window period than 4th generation tests. They can detect HIV infection around 6 to 12 weeks after exposure.
If you took a 4th generation test at 35 days after potential exposure, the result is quite reliable, but it's not considered conclusive. The general recommendation is to test again at 3 months (around 90 days) after the last potential exposure to confirm the negative result.
If you took a 3rd generation test, the result is also a good sign at 35 days, but you should test again at 3 months for conclusive results.
It's important to follow up with healthcare professionals for further testing and guidance. Additionally, if you engage in high-risk behaviors or have any other concerns about HIV, consider regular testing as part of your sexual health routine. HIV testing is crucial for early detection and timely treatment if needed.
