Question

If antibody tests are accurate 6-12 weeks after an exposure, are they still accurate 24 after?

Answer

Thank you for your question.

Yes, the tests are most accurate after 12 weeks from a possible exposure. the longer the time from exposure the more accurate they become.

For practical reasons, a negative result any time after 12 weeks is considered conclusive, even though very rarely someone might take longer that 3 months to generate an antibody response.

    i-Base no longer answer individual questions about risks of HIV transmission or HIV testing. This is because information on both these subjects is now online in two resources:
    A FAQ page on testing and transmission:
    http://i-base.info/qa/faq/hiv-transmission-and-testing
    And a more detailed but easy to read guide to testing and sexual transmission:

    You cannot get HIV from having your penis sucked. You do not have HIV. The symptoms you are being caused by something else and you should go to your doctor to find out what is causing them.
