Okay, so I had a 4th gen HIV test performed post 7 weeks exposure and an HIV RNA early detection test performed at 8 weeks. Both negative. But I am diabetic so I know my immune system has a delayed response for infections and things. So I am wondering if these negative results can be considered conclusive. Also, I got both of these tests done from online std clinics, one was from stressfreestd.com and the other from stdtestexpress.com, both web sites sent me to quest diagnostics for testing, my question is are these web sites and this lab trust worthy?
