Spanish Spoken Here, Interpretation Beyond That
Many clinics route non-English speakers through an off-site service that adds friction and delay to an already difficult conversation. Planned Parenthood California Central Coast carries Spanish-speaking staff and live interpretation for other languages directly into the care visit itself, no lag, no go-between when accuracy matters most.
Title X Covers Confidential Care for Minors
As a Title X family planning site, Planned Parenthood California Central Coast provides legally confidential services to minors: meaning care, testing, and treatment can happen without parental disclosure. That standing federal protection applies regardless of whether a young person has a regular provider or any other form of coverage.
PrEP, PEP, and DoxyPEP Prescribed at One Clinic
Planned Parenthood California Central Coast prescribes all three pharmacological prevention tools: PrEP for ongoing HIV prevention, PEP for post-exposure HIV management, and DoxyPEP. The doxycycline regimen taken after condomless sex to reduce bacterial STI risk. Having all three available at a single Title X site means prevention strategy can be calibrated precisely to a person's actual pattern of exposure.

Every Service Here Carries Zero Cost
At Community Action Partnership of San Luis Obispo, the no-fee structure isn't limited to testing: it extends across every service the clinic provides, including treatment, vaccines, PrEP, and counseling. That single policy eliminates the billing variable from every clinical decision a patient and provider make together.
Spanish and Interpretation Services on Hand
Community Action Partnership of San Luis Obispo maintains Spanish-language services directly and backs that with interpretation access for additional non-English languages: meaning clinical conversations about medication adherence, prevention options, or test results aren't filtered through a delayed channel.
Prevention Prescriptions Go Beyond the Test
Prevention-focused prescribing (PrEP for ongoing HIV risk reduction, PEP for post-exposure management) sits outside what many STI-focused clinics are staffed to handle directly. Community Action Partnership of San Luis Obispo carries both, so prevention medication is a clinical conversation happening here, not a handoff.
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 Osos, 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 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 San Luis Obispo County tests for syphilis.

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.
