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.

Stanford Children's Health in Mountain View brings STI testing through a pediatric and family health system, pairing gonorrhea, chlamydia, syphilis, and HIV screening with sliding-scale fees, same-visit bacterial treatment, and appointment-based access. With interpretation services in Spanish and other languages available throughout.
Read full overviewShow less
Stanford Children's Health offers Spanish-language services and broader interpretation support directly within the clinical encounter: meaning the conversation about symptoms, test results, and next steps happens in the language a patient uses, without routing communication through a separate layer.
Without PrEP and PEP available on-site, prevention becomes a separate referral chain. A second clinic, a new intake, a gap before medication starts. Stanford Children's Health in Mountain View manages both, keeping the prescription and the monitoring in the same practice where testing already happens.
Stanford Children's Health tests for seven infections (gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis A, hepatitis B, and hepatitis C) plus TB, giving clinicians a broader baseline from a single visit rather than requiring separate orders at outside labs.

Santa Clara Valley Dentalcare - Mountain View el Camino Real, in Mountain View, carries federally qualified health center standing: meaning its STI screening fees slide with income, keeping syphilis, gonorrhea, and chlamydia testing within reach for patients across the financial spectrum. No appointment is needed to get started.
Planned Parenthood Mar Monte in Mountain View runs a full gonorrhea, chlamydia, syphilis, herpes, and rapid or conventional HIV panel on sliding-scale fees with no appointment required, same-visit treatment for bacterial infections included, and clinical staff communicate directly in Hindi, Spanish, and Tagalog.
Read full overviewShow less
Four Languages Spoken by Clinical Staff Directly
Clinical staff at Planned Parenthood Mar Monte speak Hindi, Spanish, and Tagalog alongside English. Four languages total available for direct clinical conversation. That means medical history, treatment instructions, and prescription guidance are exchanged in the same language across the whole appointment, not relayed through a secondary channel.
Title X Legally Protects Minor Patients' Confidentiality Here
As a Title X-funded clinic, Planned Parenthood Mar Monte is legally required to provide confidential family planning services to minors. The confidentiality isn't a clinic-level courtesy but a federal statutory protection. That distinction governs how records are handled and to whom information can be disclosed.
PrEP Prescribed and Managed On-Site, Not Routed Elsewhere
Many sexual health clinics test and treat but stop short of prescribing ongoing HIV prevention, PrEP requires follow-up labs and renewals that get handed off to a primary care provider. Planned Parenthood Mar Monte prescribes and manages both PrEP and PEP directly, including coverage for uninsured patients through dedicated program funding.

Hindi and Spanish, With Interpretation Beyond
Instant Urgent Care in Sunnyvale has staff who speak Hindi and Spanish directly, with interpretation services available for other languages, so when a provider explains a medication schedule or a test result, the conversation happens in the same terms the patient already uses to reason about their health.
Prevention Prescriptions Without a Second Stop
Getting bounced to a separate prescribing clinic for PrEP can mean days of delay, and with PEP, delay has direct consequences. Instant Urgent Care in Sunnyvale manages both PrEP and PEP on-site, so prevention doesn't stall between a diagnosis visit and a prescription that never gets filled.
Hepatitis C Treatment Runs Through This Clinic
At Instant Urgent Care in Sunnyvale, a hepatitis C diagnosis doesn't end at a positive antibody result: the clinic prescribes and monitors antiviral treatment directly, meaning a patient's care plan, medication, and follow-up are managed by the same provider who ordered the initial test.

Rated 4.3 out of 5 from 26 reviews
Valley Health Center - North County in Palo Alto welcomes walk-in visits for STI screening, covering syphilis, gonorrhea, and chlamydia without requiring an appointment. Federal qualification backs its sliding-scale fees, meaning costs adjust to income for anyone who comes through the door.
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.
The nearest testing center is less than a mile away; if you'd rather skip the trip, an at-home kit ships to Los Altos, you collect the sample privately, and mail it back to a CLIA-certified lab. Results come online in days, with a clinician available if anything is positive. Same labs as a clinic, no waiting room, and you can read how accurate at-home STD tests are before you order.
Want a free option first? The CDC-supported TakeMeHome (opens in a new tab) program mails free at-home HIV self-test kits, and, in many areas, free STI kits, to your door, with no insurance or payment needed. The paid kits below add broader panels and faster turnaround.

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.

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 Santa Clara County tests for syphilis.

Los Altos wears its stability comfortably, the long driveways off South San Antonio Road, the settled households, the overwhelming majority of residents who own rather than rent. But stability doesn't automatically translate into easy healthcare logistics, and for the younger adults living here, people in their late teens and twenties navigating new relationships, getting screened quietly competes with genuinely full lives. The household picture here skews toward established, married couples with children, which shapes everything from clinic hours to how testing tends to get framed. Yet a meaningful slice of residents rent in a market where a typical monthly rent rivals a car payment in most American cities, and that cost pressure recalibrates how people weigh discretionary health spending.
Even among the city's high earners, and this is one of the wealthiest communities in Santa Clara County, a standing appointment is easier to hold when schedules cooperate. With labor-force participation sitting well below universal, a substantial share of adults juggle non-traditional hours, school pickups, or caregiving rather than a standard nine-to-five, making after-hours or weekend availability genuinely useful rather than a bonus. With the testing options listed here, someone near Creston or closer to the Whisman Station corridor can likely find something that doesn't require a long detour to fit into an already structured day.

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.
