Is it possible to wait to late to test for HIV? Can you be so ill that your tests repeatedly come back negative? I feel like I have shards of glass in my throat and the large white sore, spot on my tonsil will not go away after three different antibiotics. This is after a nasty bout of shingles for the first time in my life. I don't have strep throat or mono but my throat has never felt so sore before in my life. I am sure I have late stage HIV but test negative, is this not a possibility? I have run out of options, I need help
