Following CDC recommendations, screening is provided for these four infections because they often exhibit no symptoms, there are high quality and safe tests available, and if found positive, prompt treatment can positively impact both your health and the health of the community.

In the case of a positive test, treatment arrangements will be made promptly.

Sexual Health Resources
The clinic, along with the Longhorn Wellness Center, offers a range of sexual health resources, including a welcoming space for questions and discussion, educational materials and workshops, and free supplies.
Students can also access our library of educational resources to learn about various sexually transmitted infections (STIs). These health topics and patient education materials provide reliable information to help students make informed decisions about their sexual health.
STI Screening Timetable
How long does it take for STI (sexually transmitted infection) tests to become positive, or for symptoms to appear? The time between exposure and a positive test result—or between exposure and the development of symptoms—varies depending on several factors. Many STIs cause no noticeable symptoms at all.
The incubation periods listed in the chart below represent average time frames between exposure to positive screening test or between exposure to symptom(s). Since STIs don’t show up on testing immediately, wait to get tested to ensure more accurate results.
If you have additional questions or concerns, please contact UHS at 512-471-4955 to schedule an appointment.
