|HIV Testing - window period
Feb 13, 2012
Hi - I had an unprotected oral / vaginal exposure a month back. I had the following tests at 4 week mark:
1. HIV-1 Antibody - < 1 - Negative 2. HIV 1/O/2 Abs, Qual - Non Reactive - Negative 3. HIV-1 DNA - Negative
I have the following questions:
1. Do I need further testing or can I take these results conclusive? I have seen some websites claim that if you are negative at 4 weeks for DNA and antibody testing, no further testing is required. Is this correct?
2. If answer is yes to Question no:1, the DNA test does not cover HIV 2? So, do I still need to test further?
3. Are there any strains / versions of HIV other than 1 and 2 that these tests do not cover.
Thanks for your time

Antibodies to HIV are detected within weeks of infection. If you remain concerned, testing again at 12 weeks is fine and if negative is conclusive. The antibody test will pick up HIV-1 and HIV-2. Tests that look for HIV-1 genetic material may not detect HIV-2.
