Rated 4.3 out of 5 from 895 reviews

Carbon Health in Berkeley tests for gonorrhea, chlamydia, syphilis, herpes, hepatitis B, hepatitis C, HIV, and TB, bacterial infections treated the same visit, with fees charged on a sliding scale and no appointment required. Spanish-language care is available throughout.

Read full overview Show less

Herpes and Hepatitis Tested Alongside the Basics

Carbon Health runs herpes and hepatitis B and C testing alongside the standard gonorrhea, chlamydia, syphilis, and HIV screen. Catching hepatitis C or herpes at the same visit means treatment or management starts without scheduling a separate appointment at a separate facility.

PrEP and PEP Prescribed and Managed Here

Without a clinic that prescribes and monitors PrEP directly, patients face delays that leave prevention genuinely uncovered. Carbon Health closes that gap: PrEP is initiated and followed here, and PEP is available, so neither medication requires a hand-off to another provider.

Spanish Spoken by Staff, Not Routed Through a Line

Spanish at Carbon Health means clinical conversations (history-taking, test results, treatment instructions) happen in Spanish with staff, not patched through an outside service. That distinction shapes how accurately a patient's full history gets captured and how clearly a treatment plan lands.

Rated 4.5 out of 5 from 459 reviews

UCSF Health-GoHealth Urgent Care in Oakland takes walk-ins for a full STI panel (HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis A, B, and C) with same-visit treatment for bacterial infections; fees run on a sliding scale with Medicaid and most insurance accepted, with interpretation services on-site.

Read full overview Show less

The testing menu here runs to ten infections, adding herpes simplex and hepatitis A, B, and C to the standard HIV, syphilis, gonorrhea, and chlamydia screen. A single visit can capture that full picture, results from each test feeding directly into any treatment or follow-up managed at the same location.

For someone without an established primary care relationship, or paying out of pocket and wanting to consolidate visits, UCSF Health-GoHealth carries both PrEP and PEP on-site. The clinic can initiate or continue either medication directly, without routing through a separate prescriber.

Interpretation Services Extend to Clinical Conversations

Interpretation services are available for non-English languages, which means the conversation about symptoms, test results, and treatment options happens with full comprehension. The kind of exchange that affects whether a patient leaves with a plan they actually understand and can follow.

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.

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 Contra Costa County tests for syphilis.

About Orinda, CA

Wilder's newer streets attract some of Orinda's younger households: people still figuring out whether to stay in the hills long-term, sharing a place with a partner or roommate while the rest of the city skews firmly toward established families in owned homes. That ownership picture tells you something real: with nearly nine in ten residents holding property and two-thirds of adults married, Orinda's social fabric is unusually settled, which can make younger adults in transitional relationships feel less visible in conversations about sexual health, and less likely to seek out screening without a clear, low-effort path to do it. The financial profile here is comfortable by most measures, but $2,800-a-month rent still shapes choices for the fraction of residents who lease, particularly those in their late teens and twenties who are most likely to be navigating new relationships.

Testing options listed on this page (ranging in hours, cost, and distance) mean that planning doesn't have to be complicated. Finding one that lines up with a work schedule on the CA 24 corridor is genuinely easier than most Orinda residents assume.

Confidentiality & consent in California

Minor 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.
