Rapid HIV Testing & STD Screening


Mazzoni Center offers free, confidential, and anonymous rapid HIV testing and confidential STD screening services at our satellite 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 STDs, as well as to promote your health and well-being.

If you test positive for the HIV antibody, you will have an opportunity to meet with a Mazzoni Center specialist who can help you with accessing medical care, disclosing to partners and loved ones, safer sex, re-infection, and treatment adherence. 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 STD, information and a referral will be provided for free treatment.

Program Services

To stop the spread of STDs, it is important that those who may have been exposed are informed of their risk and can seek appropriate screening and treatment. If you have been diagnosed with an STD, there is a free online service where you can notify your sex partners by sending an anonymous or confidential e-card.

To make HIV testing and STD screening more accessible to LGBTQ communities, Mazzoni Center operates a mobile testing unit (MTU). The MTU has several regularly scheduled locations throughout Philadelphia.  

Please note, STD screening is not offered on the MTU.

     Syphilis is a disease transmitted through physical contact from person to person through oral, anal, and vaginal sex. While syphilis is easy to get, it is even easier to treat and cure with antibiotics.  Mazzoni Center offers FREE syphilis screening at our Health Center, Washington West Project, and on our Mobile Testing Unit. 

TRIP, or The Real Impact Project, is a program of Mazzoni Center and a social movement designed to raise awareness regarding sexual health among gay men and trans-identified people of color. TRIP is committed to strengthening Philadelphia's African-American gay community by producing events and promoting HIV and health awareness. Get tested and join the movement today! To learn more and get involved email Vernon Brown or call 215-563-0652 x 204.
