Take a 4th Generation Hiv Duo Test.It has a shorter window period and is a great indicator,however only at 3Months post-exposure will you receive a 100% conclusive result.Test for other STD,s aswell.All the best.
We don't use odds in this forum. We don't use them because we don't see HIV as a numbers game and what if we posted odds of 1 in 1000. Well maybe someone takes that as low risk and starts having unprotected sex and gets HIV.
The Dr's may quote numbers as they have a combined over 60 years in HIV. They have the luxory of information on many things that we do not. And of course years and oears of education, training and real world experience that we do not. So if you want you can pay and post to the expert forum.
Test at 3 months post exposure for a conclusive result. Any negative test is a good test.
