Hi there and thank you for using AIDS Vancouver Helpline as your source for HIV/AIDS related information.

First of all, I am glad to hear that you are ready for getting tested! Testing for HIV and STIs is an extremely important routine for all sexually active individuals.
Before getting into the testing information, I would like to mention that there is not yet a set of "clinically defined" HIV symptoms (aka. ARS symptoms) for health professionals to diagnose HIV. "Symptoms" vary a lot, and may not even show in some people. For those people who show symptoms, they usually experience a strong flu-like illness 2-6 weeks post exposure and that would last for only 8-10 days.

All HIV tests are equally reliable. According to many international guidelines, all HIV tests are conclusive at 12 weeks and no retest is necessary after that time mark.
PCR RNA&DNA (NAAT) is a HIV test that detects the genetic material of HIV itself, and it has the window period of 2-3 weeks of exposure. It is not so common comparing to HIV antibody tests, since it is mainly used for screening babies of HIV+ mothers and blood or organ donations.

On the other hand, you have a plenty of testing options at 4 weeks. You can get an antibody test or a Pooled RNA NAAT (Early Test).
An antibody test (3rd Generation EIA or Rapid Test) has a window period of 4-12 weeks and can detect up to 95% of the infections within 4-6 weeks.
An Early Test looks for the viral RNA and has a window period of 10-12 days. The test can detect up to 90% of the infections at 10-12 days.

If a 4th Generation EIA test is available, it can also be an ideal option for you. The 4th Generation EIA test looks for both p24 antigens and antibodies. Many HIV specialists and WHO considers 4th Generation EIA test conclusive at 6 weeks.

Again, all HIV tests are equally reliable. NO test is better than the others. Therefore, it is your option to get whatever test you prefer.

I hope I have addressed your concerns. Please feel free to write us back at any time for further assistance.

All the best,

Tina
