If you believe you have been exposed to HIV and want help to judge your risk, would like advice about HIV testing, or have questions about the effectiveness of condoms or risks associated with specific sexual practices, this is the site for you.
I was exposed to HIV in Liberia, West Africa about a year ago. Upon returning to America I had an hiv test, and another one about 5 and 1/2 months later. both were negative, but now i am reading about HIV 2 and subtypes of HIV 1. I just had something called HIV 1 and 2 screen, which includes antibody tests for both HIV 1 and HIV 2 as well as something called OD ratio. My question is, will these tests cover all types I could have been exposed to, such as group O? Also, what does OD ratio mean? Thank you.
