Patient's Query

Hello doctor,

I had a 13-day HIV (human immunodeficiency virus) DNA (deoxyribonucleic acid) PCR (polymerase chain reaction) test, a 28-day antibody test, and a fifth-week HIV fourth-generation duo test. All the tests came back negative. What are my chances of still encountering an HIV-positive test?

Hello,

Welcome to icliniq.com.

I understand your concern.

Unprotected vaginal intercourse carries a risk of 4 in 10,000 exposures. Approximately 95 % of the people who are infected with HIV develop HIV antibodies by four to six weeks of exposure, and almost all who are infected with HIV develop HIV antibodies by three months. There are rare cases of late seroconversion at six months, which is also reported in the literature. It is really good that your five-week test result is negative. Get a confirmatory test at three and six months of last exposure.

Hope this helps.

Kind regards.

Patient's Query

Hello doctor,

Thanks for the reply. I had 11 weeks and 3 days HIV antibody test, and it came negative. But I still have badly swollen tonsils, fatigue, and mild fever. What could be the reason? I am worried.

Hello,

Welcome back to icliniq.com.

I understand your query.

It is good that your test result at nearly 12 weeks is negative. Tonsillitis could be due to any viral or bacterial infection. If it is chronic, you might require an antibiotic course for five to seven days.

Hope this helps.

Regards.

Patient's Query

Hello doctor,

Thanks again. I wanted to enquire if unprotected sex would lead to throat problems as I was experiencing it for one month, but my HIV test at three months was negative. So please tell me. I have had swollen tonsils for two months.

Hi,

Welcome to iclinic.com.

I understand your concern.

You need an ENT (ear, nose, throat) evaluation for chronic tonsillitis. There are numerous causes for the same. But, it is unlikely due to HIV as your three-month test is negative.

Hope this helps.

Best wishes.

Same symptoms don't mean you have the same problem. Consult a doctor now!
