Question

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

Answer

Answer: Charlotte Walker

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.
