California has built out one of the most accessible STI testing networks in the US. Between free public clinics, sliding-scale LGBTQ+ health centers, and state-funded home test kit programmes, getting tested without cost or a doctor's referral is achievable in most parts of the state.

🏥 The Flagship Clinics

San Francisco: SF City Clinic

SF City Clinic is the city's dedicated public sexual health clinic, operated by San Francisco DPH. Testing is free for all SF residents, regardless of insurance status.

CostFree for SF residents; sliding scale for non-residents

Arrive early. Walk-in slots fill up fast. If you're outside of San Francisco, the site lists partner clinics across the Bay Area.

Los Angeles: LA LGBT Center

The LA LGBT Center (lalgbtcenter.org) offers comprehensive STI testing through its health clinics in Hollywood, Long Beach, and the South Bay. Services are available on a sliding-fee scale regardless of insurance.

📦 Home Testing: CDPH & GetYoursLA

California has invested in mail-based STI testing programmes that bring the test to you.

GetYoursLA (getyoursla.com): For LA County residents, this free programme mails complete HIV/STI test kits directly to your home in a discreet package. Order online; results via secure portal within 2–5 days.

CDPH Testing Locator (gettested.cdc.gov): For residents outside LA County, the CDC-California partnership locates free or low-cost testing sites by zip code.

Symptomatic? Go in person. Home kits are for asymptomatic screening. If you have a rash, discharge, sores, or burning, you need a physical examination and same-day treatment. A mailed kit cannot give you antibiotics.

🩸 What a Full Gay Men's Panel Covers

A complete STI screen for gay and bisexual men includes sites your clinician may skip if you don't ask explicitly. Always request:

TestSiteMethod
HIVBloodRapid or lab draw
SyphilisBloodRPR or TPPA
GonorrheaUrethra, throat, rectumSwab/urine
ChlamydiaUrethra, throat, rectumSwab/urine
Hepatitis CBloodAnnually if high-risk
Hepatitis BBloodIf not vaccinated

Say "I'm a gay/bisexual man." Many standard testing panels at non-specialist clinics only test urethral gonorrhea and chlamydia. Throat and rectal sites are missed unless you explicitly ask. At LGBTQ+ clinics, this is automatic; at general practices, you have to advocate.

🧪 Anonymous & Confidential Testing

California law guarantees your right to anonymous HIV testing at state-funded sites—no name, no ID required. Most STI testing is conducted confidentially (your name is attached, but records are protected under California Health & Safety Code Section 120975).

California is a mandatory reporting state for HIV. A confirmed positive result will be reported to the CDPH under a unique code identifier, not your name, for surveillance purposes. Your identity remains protected.
