The type of test that i think you are referring to is normally called a duo or a combo. This contains both detection of p24 antigen and antibodies. At 3 years past exposure a negative with this test is totally conclusive and would have been conclusive at 12 weeks post exposure.
You never had an exposure and you didn't need testing.
i dont think it was a DUO.. I really dont understand these things concerning HIV testing... I'm havn exams and i cant concentrate... Pliiz recommend me a 100% effective HIV test that will be entirely conclusive... >> sorry for bothering you!
This is totally conclusive, you need to give it up and get on with your studies.
