Seroconversion time for HIV

Question: 

If I got tested 5 weeks after possible exposure, and my results were negative, what are my chances of being in the clear, what is the percentage of this results being accurate?
thank you

Answer: 

Hello and Thank You for using the AIDS Vancouver Helpline as your source of AIDS/HIV related information.
The most common types of HIV testing available look for the HIV antibodies in the blood, and 95% of infections are detectable within 4-6 weeks. The test itself has a 99.8% accuracy rate after 12 weeks and there are no published accuracy percentages of test types when the test is taken before the end of a given “window period” for testing. Test results at 5 weeks can be considered quite accurate but, because there is a very small chance of getting a false result, international guidelines recommend re-testing at 12 weeks (3 months) for conclusive and definitive results. I hope this helped answer your question.
In Health,
