Hello doctor,

I took an HIV CMIA test on 26th day after a sexual encounter. The test result is negative. I had protected sex but I saw some blood on the inner parts of my partner. And also at the time I was having two pimples on my penis at the end and not on the tip. I am concern about that. Is an HIV test on 26th day conclusive?

Welcome to icliniq.com.

HIV negative test report at 26th day post-exposure is quite assuring, but, a confirmatory HIV antibody test is further required at three months of last exposure.

There are no specific symptoms by which we can diagnose HIV. The complaints which you are having could be due to multiple reasons and do not necessarily means HIV.

For the complaints you mentioned besides getting tests for other STIs (sexually transmitted infections) like HBsAg (hepatitis b virus antigen), anti HCV (hepatitis C virus), VDRL (venereal disease research laboratory), gonorrhea PCR (polymerase chain reaction), herpes simplex 1 and 2, I also suggest you to get vitamin D3 and vitamin B12 levels. Is there any fever as well? If so, please send the temperature record.

Please revert with the reports.

Thank you doctor,

Since the day of exposure, I have been taking my temperature daily. My temperature record is as follows:

Morning at 7 AM - 35.8

Afternoon at 12.30 PM - 36.4

Evening at 6 PM - 36.8.

On digital thermometer measured at armpit. All the temperature is constant since the day.

It is good to know there is no fever, however, most assuring is your negative result at 26 days. Further, a confirmation test at three months is required. Please revert with the remaining STI results.
