Great question! Unfortunately, STIs will not show up (on either a test or symptomatically) until 2 weeks after sexual interaction with an infected person.
Nonetheless, getting tested regularly is a great way to make sure you’re healthy. Many STIs can be asymptomatic, so make sure you’re getting tested even if you’re not having symptoms! While we can test for some STIs through a urine sample (chlamydia and gonorrhea) and some through a blood test (syphilis and HIV), others may require a sample from the vagina or penis, or a visual examination. (For a full break-down of what we can test for and what we can’t, check out this question.)
Teen Clinic always recommends using condoms and dental dams to help reduce your risk of contracting an STI. To make an appointment, give us a call the day before you’d like to come in. We also test for HIV once a month at each location. (HIV testing is available on the 3rd Wednesday of the month in Longmont, and the first Tuesday of the month in Boulder.)
