North East Medical Services in Daly City tests for gonorrhea, chlamydia, syphilis, HIV, hepatitis B, and hepatitis C on a sliding-scale fee open to all, with an appointment required, and delivers that care in Chinese, Korean, Spanish, and Vietnamese.
North East Medical Services conducts STI care (counseling, diagnosis, and treatment) in Chinese, Korean, Spanish, and Vietnamese without routing through an external service. That means medication adherence education and hepatitis B treatment discussions happen in the language the clinician and patient share directly.
The panel at North East Medical Services extends beyond gonorrhea, chlamydia, syphilis, and HIV to include hepatitis B and hepatitis C, and because hepatitis B treatment is available on-site, a reactive result moves immediately into a managed care plan rather than an open question.

UCSF Health-GoHealth Urgent Care in Daly City runs STI testing through urgent-care infrastructure, meaning same-day walk-in appointments, a sliding-scale fee structure, gonorrhea and chlamydia treated on the spot, and interpretation services available for non-English speakers.
Interpretation services are available for non-English languages at UCSF Health-GoHealth Urgent Care in Daly City: covering not just intake but the clinical back-and-forth around results, treatment, and next steps. The service reaches the full visit, so nothing about a diagnosis or a prescription gets lost between provider and patient.
Without both PrEP and PEP available at the same address, prevention has gaps: a patient who needs one may wait days for a separate appointment, and a lapse in either can be clinically significant. UCSF Health-GoHealth Urgent Care in Daly City holds both, so the prescription and the conversation around it happen in the same visit.
Beyond gonorrhea, chlamydia, syphilis, and HIV, UCSF Health-GoHealth Urgent Care in Daly City tests for herpes and hepatitis A, B, and C, which means an infection that would otherwise surface only at a specialist appointment can be identified here and factored directly into treatment.

STD stats & rates
How reported STI rates in San Mateo County, the county that includes Daly City, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~28% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#26 of 58 California counties for chlamydia, a higher rate than 55% of the state
| Infection | San Mateo County | California | United States |
|---|---|---|---|
| Chlamydia | 360.4 2,618 cases ▼ 27% | 491.1 | 492.2 |
| Gonorrhea | 125.3 910 cases ▼ 34% | 190.2 | 179.5 |
| Syphilis (P&S) | 9.2 67 cases ▼ 44% | 16.3 | 15.8 |
| Syphilis (early) | 11.6 84 cases ▼ 39% | 19.1 | 16 |
| Syphilis (late/unknown) | 19.1 139 cases ▼ 59% | 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 San Mateo County, chlamydia has risen from 263.1 to 360.4 per 100,000 (37%), gonorrhea has risen from 108.3 to 125.3 per 100,000 (16%), and P&S syphilis has fallen from 12.3 to 9.2 per 100,000 (25%).

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 San Mateo County.
Local HIV snapshot
San Mateo County HIV care continuum (2023)
San Mateo County recorded 12.2 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among San Mateo County residents living with HIV, 75.4% are in care · 55.4% 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 San Mateo County tests for syphilis.

Data & references
Local context
El Camino Real threads through Daly City's commercial corridor past Serramonte and toward the clinics clustered just off the freeway: a drive that can run ten to twenty minutes depending on where you're starting from in the hills, and one that genuinely requires a car in a city where walking to most destinations isn't realistic. That commute calculus matters most for younger adults, people in their late teens and twenties still navigating new relationships, because they account for a disproportionate share of STI diagnoses countywide. Daly City's households run large, averaging nearly four people, and close to half of adults are married, which means screening often involves partners and conversations, not just individual appointments. At the same time, more than four in ten residents rent, and at $2,220 a month, housing costs absorb a serious chunk of take-home pay.
Even with nearly half of households clearing six figures, that rent burden leaves limited margin for unexpected medical bills, which makes knowing the fee structures listed in the clinic cards above genuinely useful before you show up. With the testing options mapped on this page, the real task is matching one to the hours your schedule actually allows and the distance you're willing to drive on a weekday. Clinics near the Junipero Serra Freeway on-ramps tend to be the most reachable from Top of the Hill and Westlake without fighting surface traffic on Mission Street.
Getting there
At 8.34/20 on the EPA walkability index, day-to-day errands in Daly City generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
