There was no need to write a second post and Dr. Handsfield will not add his comments to ours. FYI, his comments would not differ from mine if he were to answer. We have not differed on out recommendations to a patient in many years.
Your question is repetitive. As you were told earlier, 4th generation test provides definitive evidence of the presence or absence of infection at any time more than 4 weeks after exposure.
The recommendation that only a 12 week test is conclusive is out of date in several ways. First of all, the recommendation refers to tests for antibodies to HIV. You were tested with a 4th generation test that tests for both HIV antibodies and the HIV p24 antigen. Secondly, even the recommendation that antibody tests are not conclusive until 12 weeks is also out of date. At this time, the fact is that tests for antibodies are conclusive at any time more than 8 weeks after exposure. Recommendations for longer periods of time reflect older information given from what we consider to be overly conservative agencies, including the U.S. CDC, and reflect older, out of date research.
Bottom line- as you have already been told- believe your test result, it is conclusive. You did not get HIV from the exposure you describe. EWH
