Hi, I recently had and HIV test since I had some misgivings about my status after I had an unprotected sexual encounter with someone I didn't know well. It was like 9 weeks ago. At the lab, they told me it would be an ELISA Fourth Generation test, and so, the results say I'm HIV negative, but there are some figures related to an RFV item which I don't understand well. It says my RFV is 0.02. Could anyone help me out with the interpretation of this?
