Hi there and thank you for reaching out to AIDS Vancouver with your questions. We're happy to help! It sounds like you're concerned about the reliability of your test results.

Here at AIDS Vancouver, we are not doctors or health professionals: we are volunteers who are trained in HIV related information, included transmission and testing. However, we cannot read nor interpret test results for you. If you are looking for answers regarding the reliability of your test results, it would be a good idea to consult with a healthcare professional on the matter, as they will be able to discuss your results for you.

However, here in Canada, all tests are considered conclusive 3 months after your most recent exposure. This means that the test that you took is considered conclusive. Congratulations! Furthermore, the 4th Generation Test is a very reliable and trustworthy test, and many HIV specialists around the world consider it conclusive 6 weeks post exposure. Here is some information regarding the 4th Generation Test:


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

Regards,

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. |
