Testing conclusive time

May 17, 2012


I was wondering when an antibody test is conclusive. I've read on many forums like Medhelp (Dr. HHH and Dr. Hook) and the Drs there claim 8 week is sufficient and the 3 months is outdated. Do the Doctors or experts on this forum agree? I guess the risk exposure comes in to play as well when considering window period.

Response from Dr. Hightow-Weidman

Hello there I typically advice folks that the standard for HIV tests, whether oral swab or blood are very accurate at 28 days, and conclusive at 90 days. Typically 4th generation tests can be presumed to be accurate by 2-3 weeks post exposure. Certainly I would expect it to be accurate at 2 months. In everything when you are dealing with "experts" differences in opinions arise but I don't think too different in this case. Take care, LHW
