###Human: Can HIV cause red dots in finger? ###Assistant: Hi. Firstly, I want to tell you that the tests which are done these days are highly sensitive and specific and give accurate results. Congratulations on your three months HIV test, post-exposure being negative. Numerous studies have shown that 97 % of people will have enough antibodies to accurately test positive at three months. In some of the cases, it takes as long as six months to test positive, but this is rare. Since everyone's window period is different and as per the recommendations and I also suggest to get retested at six months. Red dots on finger pits, cold and throat infection can occur in various conditions not necessarily HIV. Relax. Move forward. Just go for a repeat HIV antibody test at six months.
