Hi. I am a woman. Back in November 2016 I made a bad decision to have sex, vaginal, without a condom. It was with a man that I knew casually for about eight years. I was at the time assured by him that he had nothing and had been checked for everything last time he was seen by his doctor. After having condom-less sex with him three times I started to worry, stress, about HIV realizing that I did not really know him and that you cannot go by what someone tells you and that condoms should always be used until exclusive. So after eight weeks and one day exactly from the last encounter I had blood drawn by Quest Diagnostics for a HIV fourth generation test. The test was negative and I was relieved and went on with my life. I had no more sex with with this man. Then I felt great fear when last year I read that Biotin in high doses interferes with lab tests and cause false results. At the time of my test I have been taking 10,000 mcg of pure biotin for a couple of years because of my thin hair. I looked it up online on the Quest Diagnostics website about biotin interference and they have a list of their tests that are subject to interference by high dose biotin intake and the HIV fourth generation test is NOT on this list. My question is should I go on without another test since it’s not on their interference list? Or should I get retested. It is very scary for me as I was terrified the first time I had the test. Thanks for reading.
