When you arrive

You will be asked to provide your name, date of birth, phone number, and address (this information will be kept confidential). We will sign you up for a confidential online portal called Chexout to give you your results.

During your visit

How we test you for STIs:

A urine test – you pee in a cup
A blood test – our staff takes blood from your arm or pricks your finger
A physical exam – a healthcare provider looks at your skin, throat, and genital (private) area to check for signs of an STI
A swab test – you or the healthcare provider will swab your penis, vagina, urethra, cervix, anus (butt) and/or throat

You can get tested for STIs even if you’re not showing any signs of one. Some STIs can look alike, so you may also be tested for other infections. Our healthcare providers might be able to tell right away if you have an STI, but some results take 7-10 business days to come back from the lab. 

Chexout will tell you through text or email when your results are ready to view. Then, you can login to Chexout to see your full results. If you do not sign up for Chexout, you will be asked to return to the clinic to receive your results.

If you are asked to do additional HIV testing (through a blood draw from your arm), those results – positive or negative – are never given over the phone. We will schedule a time for you to come back to get your results.

To receive a paper copy of your records, please come to the STI/HIV Clinic during business hours.

Photo identification that matches your medical record is required.

It may take up to seven business days for your request to be completed.
