When will HIV antibodies develop in a body after exposure?

Hi, Welcome to icliniq.com.

Antibodies are the proteins produced by the body in response to fight the foreign substance (antigen, virus, infectious agent) it enters the body. When antigen enters the body, it stimulates the immune system to produce antibodies. It is very difficult to tell that how much time a particular person takes to develop antibodies. Your negative HIV antibody test at 120 days means that 99.9% of your body has not been exposed to HIV. The test kits used these days are highly sensitive and specific and give accurate results.120 days HIV negative test is highly conclusive of your negative HIV status. But, I think that you are not letting it go. The symptoms are more likely due to stress. There are very rare cases reported in the literature where the person has been exposed to antigen but the time taken by the body to produce detectable antibodies was longer, up to six months. There are recommendations and I also suggest to my patients to repeat the test at six months and if that will be negative you need not repeat it further. I hope this helps.
