How long does it take to get results form an HIV test?
I think that you’re confusing the time taken for an HIV test to show positive after exposure to the virus with the time taken to process the test results. There are certainly clinics that offer same day processing of tests. If you tested negative two weeks after taking a risk you could still be positive. However check out the link below.
The results from a given test may be back within 1-2 days (it doesn’t take long to do the test). The question may be more accurately “how long does it take my body to turn positive for the HIV test if I am infected?” That is a tougher answer, because each immune system is different. It can be as little as 2 weeks, or as long as 9 months. In general, people will get tested upon exposure and then again in 6-9 months. If it’s negative at 9 months, the odds are pretty good you are actually negative.
