question: Hello doctor, I am a 31-year-old male. I have been diagnosed with Crohn's disease before years and I have been on Humira 40 mg every two weeks. I had unprotected sex with two different girls a year ago. I have had done three HIV tests and one HIV combi Elecsys at 10 months from the last possible exposure. After a few days of the first possible exposure, I had flu. After a few weeks of the last possible exposure, I started to have some skin condition Sebopsoriasis around my mouth and under my armpit. I am also losing some muscle weight. All my HIV and Elecsys test results came back negative. My questions are: Are my tests reliable? Does Crohn's disease affect HIV test results? Being on Humira, will it affect HIV tests? Does Humira cause a false negative? Also, I know that sebopsoriasis is associated with HIV. Is there any other tests I have to do? I am under huge stress, I need your help.
