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.

Chinese Hospital in Daly City tests for gonorrhea, chlamydia, syphilis, herpes, hepatitis B, and TB on a sliding-scale fee accepted by Medicaid, Medicare, and most insurance: an appointment is required, and bacterial STIs are treated the same visit, with care delivered in Chinese and Vietnamese.
Chinese and Vietnamese are both working clinical languages at Chinese Hospital in Daly City: not supplemental services, but the languages in which providers document, counsel, and treat. For patients whose medical literacy is rooted in either language, that means nothing is filtered or compressed before it reaches them.
Chinese Hospital's panel covers gonorrhea, chlamydia, syphilis, herpes, and hepatitis B alongside the TB test: meaning infections that other panels leave for separate appointments are resolved in a single visit, and the hepatitis B vaccine is available on-site to follow a reactive result.

STD stats & rates
How reported STI rates in San Mateo County, the county that includes Colma, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~25% 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
Colma's name comes from the Costanoan word for "arrow", a nod to the land's indigenous past before it became a thriving residential and commercial hub in San Mateo. Today, the community draws strength from its multigenerational households and working families who value both convenience and discretion in their health decisions. STI testing is available in and around Colma, and the clinics and providers listed on this page understand that confidentiality matters especially to young adults navigating early careers, relationships, and life transitions. The area's character (busy, established, and focused on stability) means many residents are balancing work schedules and family time. Testing appointments that fit into weekday mornings or evenings, without unnecessary delays or awkward waits, reflect what matters here.
Whether you're newly sexually active, in a committed relationship, or simply maintaining routine screening, the testing sites nearby handle these visits with the straightforward professionalism the community expects. Colma's location and economic stability mean access to quality care without travel burden or financial strain. The providers and clinics serving this area recognize that peace of mind, knowing your status clearly and keeping that information private, is as important as the test itself. Results remain between you and your healthcare provider, with no surprise notifications or public record.

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.
