Walk-in HIV and STI testing

Mazzoni Center offers free, confidential rapid HIV testing and confidential STI (sexually transmitted infection) screening services Mondays-Saturdays at our community based testing location at Washington West Project (1201 Locust Street), and at various off-site locations throughout Philadelphia.

Our services are provided in a supportive, non-judgmental environment to assist you in identifying your HIV risks and risks for other sexually transmitted infections. You and your counselor work together to create a realistic plan to help reduce your risk for HIV and other STIs, and to promote your overall health and well-being.

If you test positive for the HIV antibody, you'll have the opportunity to meet with our Linkage to Care specialist, who can help you with accessing medical care, disclosing your status to partners and loved ones, discussing safer sex options, treatment adherence, and much more. During this session, the specialist will help you identify your emotional and concrete needs and give you referrals for Mazzoni Center services and other providers in the community.  

If you test positive for any other STI, our staff will provide you with appropriate information and a referral for free treatment.
