Thank you for your inquiry. From what we gather from the question, you were asking about the accuracy of a rapid point-of-care (POC) test that delivered a result in 15 minutes and was accessed 1 year after a potential exposure to HIV.
As I do not know the specifics of the test you accessed, I cannot answer whether an accurate result will be received after 15 minutes. If the specific test states that a result should be read after 20 minutes, then 15 minutes may not be enough time for the test to display an accurate result. If the specific test states that a result should be read after 15 minutes, then the result you received at 15 minutes is accurate. It is important to note that rapid tests can detect an HIV infection in 99% of people 3 months after exposure (1).
If you are continuously engaging in high risk activity there are biomedical approaches such as PrEP and PEP that help lower your risk of acquiring HIV. Refer to your physicians for further information.
Recommendation: Refer to a healthcare professional for more personalized answers.
