After 2 years exposure is SD Bioline HIV Ag/Ab combo test accurate


Hi I would like to firstly thank you for the great service you are doing for anxious people like us. Recently I've conducted 2 tests with SD Bioline HIV Ag/Ab combo tests and they show Negative. Is the tests conclusive for exposure which is more than 2 years ago?

Your advise is much appreciated.

HIV tests are considered conclusive 3 months post exposure. Therefore, the 2 tests that you took 2 years post exposure are considered conclusive.

I would encourage you to check out the following resources about HIV:
