HIV & STI Testing

We offer free, confidential testing for HIV, hepatitis C and sexually-transmitted infections (STIs) like chlamydia, gonorrhea and syphilis at multiple locations across San Francisco.

We provide rapid HIV testing and rapid hepatitis C testing at all of our testing locations. Those results are available in 20 minutes. Testing for STIs is also available at every location. Individuals requiring treatment are referred to Magnet, our health and wellness center in the Castro.

Everyone is eligible for our services; no one is turned away. However, we do aim to prioritize testing among communities at increased risk for HIV, STIs and hepatitis C. This includes our LGBTQIA community, trans and gender non-binary people, people of color, people who use substances, women and femmes, youth, people in the sex trade, uninsured individuals, immigrants, among others.

You can also make appointments and get your test results online.

I had a drop-in appointment today to get tested. The phlebotomist and nurse practitioner treated me with love and care. If I had to go to any clinic to get tested, this would be the first place I'd go to.

There is no fee for HIV and STI testing services. We cover the costs of our services through donations from the public, support from SFDPH, and government and grant funding.


At no point during your testing visit will you need to provide us with health insurance info or identification.

If you have health insurance and can afford to access HIV and STI testing another way, please consider your options so that we might provide services to people who do not have those same options.


Each of our sites has slight variations in testing flow. No matter which location you choose, you will be cared for by certified sexual health educators and expert medical personnel.

At registration, we ask you to fill out a form with basic information including name, date of birth and contact information. All information you provide to us is protected by HIPAA–all of our services are confidential. After you are registered for your appointment, you will be given a tablet to complete our intake survey. The intake helps us to learn more about you and your health concerns. All of the information is optional. This intake survey allows us to tailor your counseling session to your specific needs.

Once the intake is completed, a phlebotomist will collect a sample of your blood for HIV, hepatitis C, and/or syphilis testing. Post-phlebotomy, you will have the option of completing a counseling session with one of our test counselors. Your counselor can answer any questions or concerns that you have. They can also provide you with referrals to other services. If you are doing a chlamydia and gonorrhea test, this is when we collect specimens for those tests. We collect these via swab, and we suggest swabbing the parts of the body that you’re using during sexual activity. We offer a urine test as well.


HIV and hepatitis C rapid test results are received the same day that you test. All other results will be delivered via our web portal. You can expect results to be delivered to the portal within a week. If you do not have an email address and are unable to access results via our web portal, you may obtain your results in person at any of our locations.

If any of your results are positive, a nurse will contact you to set up treatment at Magnet. Treatment is provided free of cost.


We are here to support you no matter what your test result is. When clients test positive for HIV, our focus is providing them with emotional support in that moment. We understand that receiving such significant news can bring up a range of emotions, and we want our clients to know that they are not alone. We are able to link HIV-positive clients with a Health Navigation team member. Our Health Navigation team provides clients with individual support to help people take charge of your health and get the care they need. We can help people testing positive for HIV started on HIV medication on the same day.


All of the information we collect is protected under HIPAA. We will not contact you for any reason other than to provide your health results.
