###Human: Are my symptoms due to HIV infection? I had a high-risk exposure 15 months ago. ###Assistant: Hi. The test kits used to diagnose HIV are highly sensitive and specific and gives accurate results. The majority of the people who are infected with HIV (human immunodeficiency virus) develop antibodies by three months, and even in the rare instances of late seroconversions, they develop HIV antibodies by six months. You can rely on your HIV screening test results. If there had been no other exposure other than that, you do not require any further test. The symptoms which you mentioned could be due to various reasons and cannot be attributed to HIV. In fact, there are no specific symptoms or signs which can lead to the diagnosis of HIV. As per the above information, you are HIV negative. Just relax. Hope your query is answered, but if you have any other query, please do not hesitate to ask or call anytime. Best wishes.
