Welcome to the Forum.  I'll be glad to comment.  Many health care providers are confused about when HIV test results are conclusive and sometimes are making recommendations that are out of date.  Other' are merely being conservative, forgetting just how much anxiety occurs while people wait for their test results.  Combination HIV antigen/antibody 94th generation) tests are completely conclusive in persons who are not taking medications active against HIV (i.e. PrEP) at 42 days (6 weeks after an exposure.  At 4 weeks they have detected over 99% of recent infections.  Neither of us has ever seen someone who had a negative test at 4 weeks become positive at 6 weeks but we respect and support the CDC's 6 week guide.  There is no longer any reason for a person to worry that there test results might become positive if there tests are negative at 6 weeks.

I hope these comments are helpful.  EWH

thanks for your thanks.  No matter what might have been on her hands, still no risk whatsoever.  Your six week (- one day) test will be negative and prove that you had nothing to worry about. 

this is my 3rd reply.  As per Forum guidelines, the thread will be closed later today.  Take care.  EWH
