Question

How accurate is an HIV test at 10 weeks after a possible exposure?

Answer

Thank you for your question.

It depends which test you use. A fourth generation test will detect 95% of infections 28 days after a possible exposure. This needs to be confirmed by a second test 90 days after the exposure.

A third generation test (antibody only) test is accurate 6-12 weeks after a possible exposure. For more information please follow this link.

  1. Your tests were negative and this is good news. UK guidelines (BASHH) recommend that this should be tested at 90 days to confirm a negative result.

  2. hey last time plz .i tested at 9 week with antibody result was nagetive do i need to test at 12 week?plz reply?

  3. p24 antigen tests will pick up 95% of infections at 4 weeks after a possible exposure. If your test was negative then you don’t have HIV and you don’t need to test again.

  4. hey.. I have tested nagetive for p24 antigen at 3 week is this end of my testing?plz help me.

  5. 2nd generation tests are hardly used these days.
