Full information on the Washington West Community Call Center Services


Mazzoni Center receives funding to provide STI screening to trans individuals and gay, bisexual, same gender loving, queer and other men who have sex with men, with a priority on individuals of color.  Due to the higher HIV incident rates among these communities, heterosexual cisgender (or non-trans) individuals are encouraged to be screened for HIV/STIs with their primary care provider.

Mazzoni Center offers free, confidential rapid HIV testing and STI (sexually transmitted infection) screening services in a supportive, non-judgmental environment at three (3) community based testing locations.

What to Expect

  • You and your counselor will work together to identify your HIV risks and risks for other sexually transmitted infections, and 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.
