It's recommended for people between 12 and 64 to be tested for HIV at least once as part of routine health care.

There's not a single test for all STIs - each STI has its own test. Our healthcare providers determine which tests you need based on your sex history and or needle sharing practices. Clear and honest communication with your provider is encouraged for proper testing. STI testing may include:
You can get tested for most STIs whether you have any symptoms or not. Some STIs look and act alike, so you might be tested for a few different infections. Our healthcare providers may be able to tell right away if you have an STI, but most tests take seven (7) days to come back from a lab.
No, we limit examination space to the patient and the provider and or nurse. This ensures patients have a safe and confidential visit.
