I was a coward and waited a whole year to test for HIV and the Oraquick test came back negative, I also did a 4th Gen blood test and it also came back negative, but a few weeks later I was diagnosed with Hashimoto's disease :( now I'm very worried that the Hashimoto's disease may have caused false negatives in both test, should I be worried? Should I retest after my thyroid is back to normal reading? Thank you for your replies and I apologize if I sound ignorant.
