In Los Angeles County, reported syphilis runs roughly 37% higher than the US average. In San Marino, California, if you're starting a new relationship or managing ongoing care, you have multiple options: some clinics offer same-day testing for walk-ins, while labs and at-home kits let you set your own schedule. There are a number of testing options, listed below.
Available testing centers
9 testing options are listed for San Marino, CA. The nearest, CSC Community Health Center - San Gabriel - Medical Mobile Van, is about 1.4 miles away. Compare community and public clinics, private labs, and at-home kits below.
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.

Planned Parenthood Pasadena and San Gabriel Valley in Alhambra tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis B and C on a sliding-scale fee: with PrEP, DoxyPEP, and bacterial STI treatment available by appointment, all at no cost to patients.
The sliding scale at Planned Parenthood Pasadena and San Gabriel Valley compresses all the way down: testing, treatment, PrEP prescriptions, DoxyPEP, and vaccines are staffed and dispensed without a remaining balance. The operational result is that the full clinical menu, including mpox and HPV vaccines, runs at no charge.
Spanish is a working clinical language at this Alhambra location, not a routed service: staff conduct intake, counseling, and treatment conversations directly. Interpretation services extend that capacity to additional languages, meaning a patient's ability to discuss PrEP adherence or DoxyPEP timing isn't contingent on availability of outside support.
As a Title X-funded clinic, Planned Parenthood Pasadena and San Gabriel Valley is legally required to provide confidential family planning services to minors. Meaning the clinic cannot disclose those visits or results to a parent or guardian. That obligation is structural, written into the federal grant requirements that govern how Title X sites are staffed and operated.

|---|---|---|
| Chlamydia | 7 days after exposure | 14 days after exposure |
| Gonorrhea | 7 days after exposure | 14 days after exposure |
| Trichomoniasis | 7 days after exposure | 28 days after exposure |
| HIV (NAT / RNA) | 10 days after exposure | 33 days after exposure |
| HIV (4th-gen Ag/Ab) | 18 days after exposure | 45 days after exposure |
| HIV (antibody) | 21 days after exposure | 84 days after exposure |

STD stats & rates
How reported STI rates in Los Angeles County, the county that includes San Marino, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~20% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#6 of 58 California counties for chlamydia, a higher rate than 90% of the state
| Infection | Los Angeles County | California | United States |
|---|---|---|---|
| Chlamydia | 602.3 58,200 cases ▲ 23% | 491.1 | 492.2 |
| Gonorrhea | 291.8 28,195 cases ▲ 53% | 190.2 | 179.5 |
| Syphilis (P&S) | 21.6 2,085 cases ▲ 33% | 16.3 | 15.8 |
| Syphilis (early) | 33.1 3,198 cases ▲ 73% | 19.1 | 16 |
| Syphilis (late/unknown) | 50.2 4,848 cases ▲ 7% | 46.7 | 29.5 |

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.
Between 2020 and 2023 in Los Angeles County, chlamydia has risen from 529.6 to 602.3 per 100,000 (14%), gonorrhea has risen from 259.8 to 291.8 per 100,000 (12%), and P&S syphilis has fallen from 22.6 to 21.6 per 100,000 (4%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in Los Angeles County.
Local HIV snapshot
Federal priority area: Los Angeles County is one of 48 U.S. counties prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
Los Angeles County HIV care continuum (2023)
Los Angeles County recorded 19.6 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Los Angeles County residents living with HIV, 91.6% know their status · 72.8% are in care · 65.2% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
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 Los Angeles County tests for syphilis.

Data & references
Local context
Huntington Drive cuts through a city where most households own their homes outright, raising families under the same roof for years at a stretch, and that stability shapes how health decisions get made. San Marino runs on a notably married, multi-person household model, which means medical choices, including routine screening, often get folded into a broader family rhythm rather than handled alone on a lunch break. With nearly three in four households earning well above six figures and unemployment at a genuinely rare low, cost is less often the barrier here than schedule and priority.
What does create real distance is geography. The options listed on this page serve residents in and around San Marino, and reaching any of them means getting in a car and driving, which is simply the practical reality along this corridor between Huntington Drive and Las Tunas Drive. For younger adults in their late teens and twenties, people still building relationships and navigating new situations, that drive becomes the thing most likely to cause a test to be delayed rather than skipped entirely. Keeping the nearest clinic's hours on hand and knowing what to bring makes the trip more routine and less of a project.
Los Angeles County carries STI rates that reflect the scale and density of the region as a whole. For someone living in a quieter pocket like San Marino, where daily life can feel removed from that broader picture, the county figures are a useful reminder that staying current matters not because risk is visible, but precisely because it often isn't.
Getting there
San Marino scores 13.87/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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).
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
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.
