Can a negative STD panel test after 46 days be conclusive?

Question

Hello doctor,

I was having vaginal sex and the condom broke in between and I stopped immediately. Some other details which I want to share are as follows:

I did a full STD panel test four times on the 13th, 26th, 35th, and 46th days after the exposure. All the results were negative.
After 21 days of exposure, I had a viral fever and a bad throat. The fever was for two to three days but the bad throat persisted for a week. I took antibiotics and Paracetamol for my viral fever and bad throat.
The woman with whom I was having sex showed me her HIV-negative result which dated two months back from the date of exposure. According to her, she is negative but I am not sure. She got tested at a government hospital.
STD panel included an HIV combo test (CMIA) which looks for antibodies and antigens (p24) as well.
I have asthma but I do not take any medicines for that. I keep it controlled by exercising and running regularly. Also, I do not take any regular medicines or any kind of drugs or steroids.

I have a few questions:

Some doctors say HIV combo tests are conclusive anytime after 28 days but some say it can take months to develop antibodies and that antigen tests are not that reliable. Can you please clarify this?
Can I consider my tests conclusive or is retesting required?

Answer 1

Hello,

Welcome to icliniq.com.

Thank you for your query.

The chances of transmission of HIV (human immunodeficiency virus) by a single unprotected intercourse are low. Condom breakage can be considered almost unprotected intercourse. A 4th-generation HIV antibody test is negative repeatedly, and after one month of exposure, it is almost considered conclusive. The chances of an HIV test coming positive later are almost nil. The antigen can be formed and can wane away, so it may not be considered reliable many times. HIV antibodies take two to six weeks to form.

A maximum of three months is given for this detection. So it is better to go for an HIV antibody test after 90 days of exposure to be relieved of anxiety totally and have conclusive results. The symptoms are non-specific and need not be due to HIV. It can be due to any infection. There is nothing to worry about regarding asthma affecting HIV test results.

I hope this has helped you.

Thank you.
