ZoomCare in Redmond runs on scheduled appointments, and a single visit covers the full panel (HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis A, B, and C) with same-visit treatment for bacterial infections, sliding-scale fees, and insurance accepted.
ZoomCare draws herpes serology and hepatitis A, B, and C antibody tests through the same appointment as the core bacterial and HIV panel. That means one blood draw, one visit, and results that cover the infections most clinics ask you to schedule separately.
ZoomCare Redmond prescribes and manages PrEP, PEP, and DoxyPEP, all three prevention medications, without requiring a separate infectious-disease provider. For someone without a standing primary care relationship, that's a single practice writing the prescription, tracking adherence, and handling follow-up labs.
Interpretation services at ZoomCare are arranged as part of the appointment workflow, not improvised at the desk. The clinical conversation (exposure history, medication instructions, test counseling) runs through a staffed interpreter so the clinical record reflects what was actually communicated.

Sea Mar Community Health Centers in Bellevue tests for gonorrhea, chlamydia, syphilis, and hepatitis, with same-visit treatment for bacterial STIs, on a sliding-scale fee open to everyone. Appointments are required, and care is delivered in Spanish.
Sea Mar conducts STI care in Spanish, meaning clinical conversations (symptom history, treatment decisions, follow-up instructions) happen in that language without an intermediary. That directness keeps nothing lost between what a patient says and what the provider acts on.
Sea Mar carries substance-use treatment as a named service alongside STI care, so both conditions are addressed within the same clinical relationship rather than managed through separate providers. A single care team holding both makes coordinated treatment decisions (medication interactions, overlapping risk factors) rather than working from incomplete information.
Sea Mar tests for hepatitis A, B, and C, including a rapid hepatitis C test, on top of the standard bacterial and HIV panel. Hepatitis C rapid testing returns results in the same visit, compressing the window between screening and knowing.

Bel-Red Internal Medicine in Redmond pairs gonorrhea, chlamydia, syphilis, hepatitis B and C, and HIV testing with same-visit bacterial treatment, PrEP, and PEP. All on a fee-for-service basis with appointments required.
Bel-Red's standing as an internal medicine practice means PrEP and PEP are prescribed, monitored, and followed up by the same provider over time. The right fit for someone who wants prevention medication managed within a continuous care relationship rather than a one-off visit.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Bel-Red tests for both hepatitis B and hepatitis C in the same appointment. Hepatitis C is identified through antibody testing and any reactive result can be managed directly within the practice, keeping follow-up care with the provider who ordered the test.

Public Health Seattle and King County in Bellevue tests for gonorrhea, chlamydia, syphilis, and HIV on a sliding-scale fee structure accepted by Medicaid, Medicare, and most insurance. Appointments are required; bacterial infections can be treated the same visit.
When a language gap forces someone to return for a follow-up they never book, an STI goes untreated and a cycle of exposure continues. At Public Health Seattle and King County in Bellevue, STI care (testing, counseling, treatment) is delivered directly in Spanish, closing that gap at the first visit.
Leaving substance-use treatment off the table means a patient clears one diagnosis and walks back into the conditions that drove the exposure, and often returns months later with the same or a new infection. Public Health Seattle and King County in Bellevue carries substance-use treatment alongside STI care so both are addressed in the same clinical relationship.

International Community Health Services in Bellevue tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis A, B, and C on a sliding-scale fee open to everyone; appointments are required, bacterial STIs are treated the same visit, and care is delivered in Chinese, Spanish, Tagalog, Vietnamese, and additional languages.
International Community Health Services carries on-site hepatitis C treatment alongside diagnosis: meaning patients without a specialist, without a primary care relationship, or paying out of pocket don't face a gap between a confirmed result and the medication that clears the infection.
The prevention pharmacy at International Community Health Services spans daily oral PrEP for HIV, post-exposure PEP, and DoxyPEP taken after potential bacterial exposures: each requiring its own prescribing schedule, lab monitoring, and adherence support that the clinic provides directly rather than coordinating across separate providers.
When a nuanced conversation (about a symptom timeline, a medication side effect, or a prevention regimen) gets lost in translation, the clinical outcome suffers for it. At International Community Health Services in Bellevue, care is delivered directly in Chinese, Spanish, Tagalog, and Vietnamese, with interpretation available for other languages, so the medical conversation stays intact from the first question to the final prescription.

STD stats & rates
How reported STI rates in King County, the county that includes Sammamish, compare with Washington 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.
#18 of 39 Washington counties for chlamydia, a higher rate than 54% of the state
| Infection | King County | Washington | United States |
|---|---|---|---|
| Chlamydia | 324 7,360 cases ▼ 9% | 354.4 | 492.2 |
| Gonorrhea | 198.5 4,509 cases ▲ 53% | 129.6 | 179.5 |

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 King County, chlamydia has fallen from 373.4 to 324 per 100,000 (13%), gonorrhea has risen from 192 to 198.5 per 100,000 (3%), and P&S syphilis has risen from 14.8 to 25.4 per 100,000 (72%).

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 King County.
Local HIV snapshot
Federal priority area: King 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.
King County HIV care continuum (2023)
King County recorded 9 new HIV diagnoses per 100,000 (2023), against 6.3 statewide and 13.7 nationally. Among King County residents living with HIV, 88% know their status · 87% are in care · 79.1% 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 King County tests for syphilis.

Local resources & officials
Data & references
Local context
Sammamish households skew toward long-term partnerships and larger families, and in a city where nearly three-quarters of adults are married, health decisions rarely happen in isolation. Scheduling a screening means coordinating around a partner's calendar, school pickups along WA 202, and a household routine built around kids and careers rather than personal spontaneity. That shared-life architecture can nudge individual health habits to the back of the queue, even when intention is high. That matters especially for younger adults in their late teens and twenties, people still establishing relationships and sexual histories, who benefit most from routine, low-threshold testing. With over four in five Sammamish households earning well above the six-figure mark and unemployment unusually low, cost is rarely the sticking point.
The real constraint is schedule density: a labor force that participates at high rates, in homes that run like small organizations, where a mid-week afternoon appointment can feel harder to carve out than it sounds. The options listed on this page span different hours and formats precisely because that kind of calendar pressure is real in neighborhoods like Klahanie and Pine Lake. King County's STI data captures why access has to work around people's actual lives, not ask them to rearrange those lives. A clinic that fits between a Beaver Lake Park trail run and the afternoon school run is the one that actually gets used.
Getting there

Two things that actually depend on Washington 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 Washington, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Washington 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.
