Hi, first of all thank you for providing all the information.
7 weeks ago I received unprotected oral from a female. We also kissed and did a mutual masturbation. No vaginal or anal sex.
12 days after encounter I had a fever for about 48 hours and blood discharge from my belly button(also for 2 days). On day 14 I was really anxious about being infected so I went to do a HIV test in clinic. It was a ECLIA antibody test. Result was negative. My fever that day also disappeared and I slept so well. On day 15 I woke up in middle of the night with a sweat on my neck and forehead. I had a weird dream about HIV so I think it was because of this.
Then after 5 weeks (day 35) I went to test again.
This time I tested with Architect HIV 1,2 Ag/Ab test. Result was negative as well. Doctor told me that because I had a "negligible risk" encounter I don't have to test again.
My question is:
The doctor told me that, if the symptoms that I experienced would be because of the HIV infection, I would already test positive because my body already would fight with the virus. Is that true ?
Should I test one more time at 8 weeks with Ag/Ab test or should I test later when I will go for a regular testing (I test every 6 months).
Thanks for answering.
Hello and thank you for your inquiry.
We understand that you would like to know if a 4th generation HIV Ag/Ab test you received 5 weeks after receiving oral sex can be considered conclusive.
We agree with the doctor that receiving oral sex is a Neglibigle Risk encounter, meaning that there is a potential for HIV transmission, but there has never been a confirmed report of transmission from this activity.
Seroconversion is the period of time during which HIV antibodies develop and become detectable. It is often, but not always, accompanied by flu-like symptoms including fever, rash, muscle aches and swollen lymph nodes. These symptoms are not a reliable way to identify seroconversion or to diagnose HIV infection. (2) If your symptoms are actually attributed to seroconversion, then your blood should test positive for HIV antibodies.
Fourth-generation HIV tests can detect HIV infection in 50% of people by 18 days after infection; 95% of people by 34 days after infection; and 99% of people by one and a half months after infection. Fourth-generation HIV tests and the INSTI rapid test have a sensitivity of about 99.9%. (1)
Recommendation: Since this is a negligible risk, you have already tested negative at 5 weeks post encounter, and have already consulted your doctor, no further action is advised.
