Hello and thank you for contacting the AIDS Vancouver Helpline. I am happy to answer your questions.

Firstly, congratulations on getting tested and getting a negative result! In your post it sounds like you are curious about the number of tests that need to be taken to determine your HIV status, and if that status can change over time. I will break it down for you.

By using the BCCDC standards for HIV testing, they say that HIV test results can be considered conclusive 12 weeks post-exposure. For this reason, you may only need to take *1 test* to determine your status, as long as it occurs outside of that window period of 12 weeks. Note that it is the time that the test is taken that is important, rather than the number of tests taken. Since you had multiple tests *close to and after the 12 week mark*, you may consider your results conclusive. You do not require further testing. Furthermore, the 4th generation tests are very reliable and accurate, and most HIV specialists consider it conclusive after only 6 weeks.

A negative test result after 12 weeks is very unlikely to change unless you fall into one of four categories that alter window periods. These categories are: if you are taking antiviral treatment for hepatitis C, if you are undergoing treatment for cancer, if you are taking PEP for HIV, or if you have an immunodeficiency disorder. If none of these categories applies to you, the chances are small for your results to change (in that case, the tests would have to have somehow been done incorrectly, but this is unlikely if done by professionals). Since you have had multiple tests after the 12 week window period, it is unlikely for your test results to change- at this point they are 99.9% accurate!

I hope I have answered your questions to your satisfaction and provided you with enough information to move forward. If you have any more questions, do not hesitate to contact us again!

Sincerely,

Caroline
