How to read these listings
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Spanish Spoken Directly, Interpretation for Others
Spanish is a working language at this Antioch location, not routed through an external service.

Title X Means Legally Confidential Care for Minors
As a Title X-funded site, Planned Parenthood Northern California in Antioch operates under federal confidentiality law, which means a minor's STI testing, contraception, and family planning services are legally protected from disclosure to parents or guardians, not as a policy preference but as a statutory requirement built into the funding structure.
PrEP and PEP Prescribed On-Site Without a Specialist
Planned Parenthood Northern California in Antioch carries both PrEP, the daily medication that prevents HIV acquisition, and PEP as standing clinical offerings, with prescribing, coverage navigation for uninsured patients, and ongoing PrEP monitoring handled at the same location rather than requiring a separate infectious disease provider.

Contra Costa Health Services in Pittsburg functions as a county public health clinic, which means STI care sits alongside family planning, HIV treatment, and medication counseling in a single appointment-based system: with a sliding-scale fee structure, same-visit treatment for bacterial infections, and staff who see patients in Laotian, Spanish, and Vietnamese.

Herpes Testing Alongside the Standard Four
The panel at Contra Costa Health Services covers gonorrhea, chlamydia, syphilis, HIV, and herpes. Five pathogens, not four. Herpes diagnosis shapes treatment decisions and partner conversations in ways the standard panel simply can't, and having it built into the same appointment removes a separate specialist visit from the equation.
PrEP and PEP Available Where Many Clinics Stop
Many STI clinics test and treat but leave HIV prevention prescribing to outside providers. Contra Costa Health Services handles both PrEP and PEP directly, so prevention and care stay in the same clinical relationship rather than splitting across separate practices.
Laotian, Vietnamese, and Spanish Spoken by Staff
Clinical staff at Contra Costa Health Services see patients in Laotian, Spanish, and Vietnamese: meaning that for speakers of those languages, medication adherence counseling, test results, and prevention education all happen in a direct conversation, which strengthens follow-through on treatment plans.
La Clinica Pittsburg - Medical, in Pittsburg, carries federal qualification as a community health center, which means STI screening for syphilis, gonorrhea, and chlamydia is available on a sliding-scale fee tied to income, so out-of-pocket cost adjusts to what each patient can actually pay.

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 Contra Costa County residents living with HIV, 80.2% are in care · 73.4% 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 Contra Costa County tests for syphilis.

Antioch tilts toward ownership, most households here carry a mortgage rather than a lease, but a substantial renting population navigating $1,700-plus monthly costs knows exactly how competing financial pressures reshape what gets scheduled and what gets postponed. That renter share skews younger, more mobile, and more likely to be in the late-teens-to-late-twenties window when STI transmission tends to peak, which makes accessible screening less a convenience and more a structural necessity for this city. Unemployment here runs meaningfully above the state norm, and labor-force participation leaves a notable slice of working-age adults outside the traditional employer-benefits pipeline. Meaning clinic hours and sliding-scale fees aren't abstractions but the actual deciding factors in whether someone follows through.
With the testing options listed on this page, Antioch offers genuine variety: community sites near Lone Tree Way, options reachable from Sterling Pinnacle, and providers that serve people whose schedules don't conform to a standard nine-to-five. Larger household sizes here (families under one roof, shared costs, shared schedules) often mean health decisions get layered into already crowded weeks. The clinics on this page reflect that reality, and finding the one that fits the drive from Contra Loma Park or the commute back down East 18th Street is the first concrete step.

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.
