|Post Pep Testing @ 6 weeks, 12 weeks, 24 weeks!
Nov 25, 2009
I am fully aware that post PEP HIV antibody testing should be carried out at 6,12 and 24 weeks from exposure for a conclusive result.
Do you know of any cases where earlier negative tests have gone on to be positive at later stage? If so, how frequent is this occurance?
It is clear that the 24 week should only be used as conclusive BUT if the cases of delayed positive testing are remote then this might give people 'some' comfort and reduce the anxiety during the time of uncertainty they face.

No, with over 25 years of clinical experience, I have not seen a case where someone with negative post-PEP testing out to 24 weeks subsequently tested HIV positive (without additional HIV risk).
