Patient's Query

Hello doctor,

I had a possible exposure to HIV eight months ago. The exposure was that I had shared a cigarette with someone who might be HIV positive. It has been six months since, and I got tested 12 to 15 times. All the tests were blood drawn from my vein and 4th generation tests were done. All the tests were negative. The latest 4th generation test was done this month, which was on the 218th day, and it was negative. Six months ago, I was diagnosed with ulcerative colitis, and I have been taking medications for the same since then.

1) Is it by any chance possible that I still have the virus and it is not showing up on tests?

2) Is it possible that I could get HIV from sharing a cigarette, where a few particles from the HIV-positive person came onto the cigarette bud and from there to my oral mucosa (lips)?

3) Is it possible that my medications for ulcerative colitis could alter my results and it is resulting in a false negative?

Hello,

Welcome to icliniq.com.

The risk of transmission of HIV (human immunodeficiency virus) by the given description is almost nil. The HIV 4th generation test is repeatedly negative after three months of exposure. As there is no further risk exposure it is conclusive. There is no need for further HIV tests. I do not think, there is a possibility of HIV tests being false negative with medications of ulcerative colitis. Just forget about HIV and lead a normal life.

Thank you.
