University of Washington Medicine in Bellevue accepts Medicaid and private insurance, with fees scaled to those without coverage, and runs a full panel (rapid and conventional HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis A, B, and C, and TB) by appointment, with care available in Chinese.
University of Washington Medicine in Bellevue delivers STI care directly in Chinese, not through an intermediary service but as a standing clinical capability. For someone navigating a PrEP regimen, a hepatitis B diagnosis, or medication adherence counseling, conducting that conversation in Chinese means nothing gets simplified away.
PrEP, whether tenofovir-based Truvada or Descovy, requires the HIV testing, kidney-function monitoring, and prescription renewals that keep it working; University of Washington Medicine in Bellevue handles all of that directly. PEP, the post-exposure course, is likewise prescribed on-site, meaning both ends of HIV prevention live in the same chart.
When hepatitis C treatment requires a separate specialist referral, weeks pass between a positive antibody result and the antiviral prescription that actually clears the infection, and some patients never close that gap. University of Washington Medicine in Bellevue treats hepatitis C on-site, so the confirmed diagnosis moves directly into a treatment plan rather than a handoff.

STD stats & rates
How reported STI rates in King County, the county that includes Newcastle, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% 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 |
| Syphilis (P&S) | 25.4 578 cases ▲ 19% | 21.3 | 15.8 |
| Syphilis (early) | 18 409 cases ▲ 44% | 12.5 | 16 |
| Syphilis (late/unknown) | 29.1 660 cases ▲ 27% | 22.9 | 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 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.

Data & references
Local context
Coal Creek Parkway Southeast curves past the Wilderness Peak trailhead on its way down toward Bellevue and Renton, and most of the clinics listed here sit within a fifteen-to-twenty-minute drive along that corridor or out on WA 900. Close enough that a lunch break or an errand run can realistically cover a visit without a separate trip. That convenience matters because Newcastle skews heavily toward long-term residents with deep roots: nearly three in four households own their homes, and most are married couples sharing space with children or other family members. That settled, two-income character also means schedules are dense. Both adults working, school pickups, weekend commitments.
For younger adults in Newcastle, the ones in their late teens and twenties building relationships and still figuring out what routine healthcare looks like, a clinic that fits between two other stops on Coal Creek Parkway is far more likely to actually happen than one requiring a dedicated half-day. Rent here runs well above typical, and even in a community where most households earn comfortably, that cost pressure shapes priorities. A sliding-scale or low-cost option among the listings removes the calculation entirely, no weighing a co-pay against something else. Neighborhoods like Olympus and The Highlands at Newcastle are quiet and residential; the clinics nearby on WA 900 serve as the practical anchor for most of that eastern hillside.
Getting there
Newcastle scores 11.07/20 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.

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.
