i had high risk sex many times with unknown girl and got checked up myself for hiv on 5th month, 6th month, seventh month and 8th month all came negative. i did hiv elisa 4 gen and western blot test. And now its been a year from a time when i had high risk sex. But i got scalp folliculitis and one large swollen nodes on my neck just behind ear from more than three months which is not going away. so I also have heard that hiv infected people develop the swollen nodes on neck and also the hair issues. Is this true??? are all my test result is conclusive ? do i need to checked up for hiv again??
Hi there and thank you for reaching out to AIDS Vancouver with your questions. We're happy to help!

Here in Canada, all tests are considered conclusive 3 months after your most recent exposure. This means that all of the HIV tests that you took are considered conclusive. Congratulations!

Here is some information regarding the tests that you took:

Test Name Method Window Period Conditions
4th Generation EIA Blood test that looks for antibodies AND p24 protein antigens. Commonly referred to as the "combination," "combo" or "DUO" test. P24 protein is detectable immediately after infection but only for the first few weeks. The antibody (ab) test has a window period of 4-12 weeks post exposure. This test is widely available in North America. Most HIV specialists consider this test to be conclusive at 6 weeks but official HIV testing guidelines still recommend re-testing at 12 weeks for conclusive results. Conclusive at 3 months post exposure.

I also wanted to briefly address your symptoms: there are no specific symptoms of HIV. In fact, certain individuals may never develop symptoms, and for those who do, most symptoms will go away after a few days, or at most, a couple of weeks. This is why the only way to diagnose HIV is to get tested. Because HIV symptoms mirror so many other viral infections or can be explained by other things, we do not go by symptoms here at AIDS Vancouver.

I hope I have answered your questions, and feel free to contact us with any further concerns.
