Actually the Advia Centaur HIV 1/o/2 test is approved by the FDA.

Hi Teak, I had my test done through tstd.org, and on Labcorp's result sheet, it says they used HIV 1/o/2 test as well. This is not FDA approved? Should I not rely on my 7 and 13 week negative test?
Assay for the Detection of Antibodies to Human Immunodeficiency VirusType 1, Including Group O (HIV-1 + “O”) and/or Type 2 (HIV-2)
It's not and FDA approved test in the US.
