I’m sorry you’re still feeling unwell. It sounds as if you have had many many HIV tests and they were all negative except for the first rapid test. It’s hard for us to comment on the accuracy of tests (like your brand of rapid test) that we do not use here in British Columbia. We do know it is possible to have a false positive on a rapid test (or any test), which is why we do further testing to confirm a result. From what you wrote, it seems like you had confirmatory testing, like the elisa and western blot, and that by then you were out of the 3-month “window period“, and that they were all negative. It can be worrisome to see a positive result, but it sounds like you did the right follow up and that this is not a true HIV positive.
However, if you have rash, joint pain, and throat pain for 10 months, we do recommmend you keep going to your doctor to figure out what might else be causing this.
Hope that is helpful,
