How log should I wait after a potential HIV exposure before getting tested?

4 to 6 months. Best time to get a good test us 4 to 6 months.
Right away. It's good go get tested right away for baseline testing, and then to be tested 4 to 6 weeks later again. Some lab tests can detect a new HIV infection within a few days, while others require a few weeks... It really depends on which test the doctor orders.
