Hello, I have some questions about HIV test. I have an oral and vaginal sex with a hooker on June 4, she also licks my anus for a short while and I inserted my finger into her vagina for about 3 seconds. I wore condoms for most of the oral and the whole vaginal sex. two weeks later i had a fever which ran from 101.3 to 102.4,it lasted for 2 weeks and had a 3 day remission after the first 6 days of fever. The fever happened at afternoon and night but not in the morning. On July 3rd, I began to have severe thorat sore and multiple oral ulcerations. the sore and ulceration was so bad that I cant even talk or eat. it lasted 9 days. On June 6th, I began to take some zinc supplement for the ulceration. I had HIV Ab immunofluorescence test on Day 1, 17, 21. 28, 35,42 and 56 after the sex and all came back negative. Today I went online and some people told me the supplement I take might contain corticosteroid and it made me feel good. But it actually will delay the seroonversion and made the test results a false negative. I quit taking it today. I live in China and went to see a HIV specialist here. He told me I was OK and any adult tested negative 6 weeks after exposure is a sure negative and dont need to get further test unless he or she is a drug user or had a major surgery recently .
My question is: If the supplement does contain corticosteroid, and I have used it since 31 day after exposure, will it interfere with my test results? Do I need to repeatedly get tested? Or the 8 week test is conclusive? Do you favor what the Chinese HIV specialist say about the 6 week window period is good for everyone?
