Interpretation Services Built Into Every Appointment
For anyone whose primary language isn't English (whether navigating a new diagnosis, asking about treatment options, or weighing prevention) interpretation services are available at UCSF Health-GoHealth Urgent Care without rerouting the visit. That standing capability means the clinical conversation happens in real time, with the provider, not as an afterthought.
PrEP and PEP Prescribed and Monitored On-Site
PrEP at UCSF Health-GoHealth Urgent Care involves the full clinical loop: initial HIV testing to confirm eligibility, a prescription for daily oral medication, and the follow-up labs, typically HIV and kidney function, required to continue it safely. PEP is likewise prescribed on-site, meaning the course of antiretroviral medication starts without handoffs to another provider.
Herpes and Hepatitis Testing Beyond the Standard Four
For anyone without a regular primary care provider, or paying out of pocket and trying to do a genuinely complete workup, UCSF Health-GoHealth Urgent Care's panel extends to herpes simplex, hepatitis A, hepatitis B, and hepatitis C alongside the core bacterial and HIV tests. That matters when a single visit needs to cover ground a basic panel won't.

Spanish is spoken directly at Marin Community Clinics, and interpretation services extend that reach to other languages. The practical effect: sexual health history, treatment instructions, and follow-up questions move in the language a person speaks without a gap between the clinician and the conversation.
Ryan White Funding Covers HIV Care Start to Finish
Ryan White funding at Marin Community Clinics means HIV care doesn't stop at a positive test, ongoing treatment and management are covered under the same program. For someone without a regular HIV provider or facing cash costs for antiretrovirals, this is where the full continuum lives.
Marin Community Clinics carries both PrEP and PEP as standing services, meaning someone who wants ongoing HIV prevention, or needs PEP managed through a provider, doesn't have to piece together a prescription from a separate source. Both are prescribed and followed here, which matters most for anyone without an established primary care relationship.

Chinese-Language Care From Test Through Treatment
North East Medical Services conducts testing, counseling, and treatment in Chinese. Meaning anyone whose primary language is Cantonese or Mandarin can navigate medication decisions and follow-up care without relying on a go-between. For someone without a regular provider and managing care through a sliding-scale clinic, that continuity across the full visit changes what's actually possible.
Hepatitis C Treated Here, Diagnosis to Cure
North East Medical Services carries hepatitis C treatment on-site, which matters acutely for anyone without a specialist or a primary care relationship who needs to move from a positive result to antivirals without navigating a separate system. The sliding-scale fee structure applies to treatment as well, so cost doesn't become the reason a curable infection goes unmanaged.
Hepatitis A, B, and C Added to the Standard Panel
Clinics focused strictly on the bacterial and viral STI basics leave hepatitis testing to a separate appointment or a separate provider entirely. North East Medical Services tests for hepatitis A, B, and C alongside gonorrhea, chlamydia, syphilis, and HIV, and pairs those tests with vaccination for hepatitis A and B and treatment for B and C.
Beyond the dedicated testing centers above: at-home kits by mail, hospital labs certified for STI testing, local clinicians who can order a panel during a regular visit, pharmacies for self-test kits and prescriptions, and online PrEP & treatment.

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.

Among Marin County residents living with HIV, 74.8% are in care · 71% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.

Pregnant or planning to be?Congenital syphilis is the fastest-rising STI: what to test, and when
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Marin County tests for syphilis.

Renters make up the overwhelming majority of Marin City households: people navigating $1,662-a-month leases in a corridor tucked between Sausalito and the Redwood Highway, where roommates and shared costs are simply part of the calculus. For younger adults sorting out new relationships and first independent living arrangements, that kind of budget pressure means health appointments often get weighed against rent, groceries, and every other line item. When screening is low-cost or free, and when it doesn't require burning half a workday, it actually happens.
The household picture here is telling: average households run larger than the national norm, and fewer than four in ten adults are married, which reflects a community with plenty of people in transitional or non-partnered arrangements. Exactly the life stage when staying current on STI screening matters most. With nearly two-thirds of residents in the labor force, the options listed on this page need to fit around real work schedules, not just exist in theory.

Confidentiality & consent in CaliforniaMinor consent and partner treatment (EPT) under state law, plus how to test privately
Two things that actually depend on California law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
Can a minor consent on their own?
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
California permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
