Is HIV Ab/Ag Combo Test After 12 Weeks Of Exposure Accurate?

Question: Hi dr kakkar as yoh would know that i was worried about possible about hiv infection even though my risk was very less (since i used protection but had inprotected oral) i got tested after 5 weeks and inmediately after 3 months post exposure both were non reactive.. Im attaching the report and would like to know that is the test suffuciebt considering the window period against both hiv 1 and hiv 2 plus i got the sevind tesy at exactly 12 weeks after exposure ie 84 days do you think i need to give it again.. Please help me out as i am still a little nervous
Brief Answer:
This test is conclusive and no further testing is required
Detailed Answer:
Hi. Thank you for writing back.
I have reviewed the attached report. It is a an Hiv Ab/Ag combo test i.e it tests for both anti- Hiv type 1 & 2 Antibodies and P 24 Antigen.
All Hiv infected individuals will have detectable circulating antibodies at 12 Weeks. Therefore a negative antibody test Or an antigen/antibody combo test at 12 weeks rules out Hiv conclusively.
This test is conclusive in your case since it covers for the window period (i.e 12 weeks for an antibody based test) for detection of Hiv by an antibody based test.
So you can now completely stop worrying about Hiv.
Regards

Dr kakkar i do sometimes feel that im peeing a bit more than usual but not more than an average 5 6 times a day..alak there is sometimes a slight heavy feeling there as if pee is about to come sometimes but not always my blood report and urine report were absolutely fine and there id no irritation or pain while peeing also no marks or rashes down there so is there any other std related thing that i could possibly cause this
