4. Some STDs might not show up until months after exposure
There are different recommended testing times for different STDs, so it’s important to talk to your doctor about when your most recent sexual encounter was. This will help your doctor determine the best time to actually perform the test, based not only on the timeline you provide, but also the kind of test you’re requesting. For example, One Medical suggests waiting two weeks for gonorrhea and chlamydia, one week to three months for syphilis, and six weeks to three months for HIV, hepatitis C, and hepatitis B.
