Hello. I was wondering if it's possible to have a false-negative HIV test a year and a half after exposure. About a year and a half ago I had unprotected sex with a girl I didn't know and two weeks later I was covered in hives and had the worst sore throat and headache of my life. This lasted for about three days then went away completely. I told my doctor this and took about every STI test available and they all came back negative. I didn't actually get the results from my doctor so I didn't have a chance to ask him if the single HIV test is 100% accurate, or if I should have another one done. Do you think that is necessary? Thank You.
Thanks for the quick reply! So is there something else I could have contracted from the exposure that causes the symptoms above? Or do you think it's safe to say it was just a coincidence that I had those symptoms at that time?
