Available testing centers
7 testing options are listed for Hat Island, WA. The nearest, WhidbeyHealth, is about 3.9 miles away. Compare community and public clinics, private labs, and at-home kits below.
WhidbeyHealth in Clinton takes walk-ins for HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B, hepatitis C, and TB testing, with same-visit treatment for bacterial STIs; fees run on a sliding scale and Medicare and insurance are accepted.
WhidbeyHealth carries both oral PrEP regimens and PEP, meaning the prescription, follow-up labs, and ongoing HIV-prevention management stay with the same provider rather than splintering across separate appointments. Staying on PrEP requires quarterly or biannual HIV and kidney-function monitoring, WhidbeyHealth handles that continuity directly.
Leaving herpes or hepatitis C undetected means a person carries a transmissible infection with no treatment clock started, at WhidbeyHealth in Clinton, testing for both is part of the same walk-in visit as the standard bacterial panel, so there's no second appointment at a separate lab to close that gap.

Providence in Everett operates within an integrated health system, anchoring STI care (gonorrhea, chlamydia, syphilis, HIV, hepatitis B and C, and TB) in a clinical environment that pairs same-visit bacterial treatment with sliding-scale fees. Appointments are required. PrEP and PEP are available.
Providence prescribes Truvada and Descovy for PrEP, along with PEP, and handles the follow-up lab work, HIV and kidney function monitoring at 90-day intervals, that keeping someone safely on either regimen requires. Staying within one system means those results inform the prescribing clinician directly.
Providence's standing capability includes hepatitis C treatment, not only diagnosis. The antiviral prescribing and follow-up that clears the infection happen at the same site as the initial test. For anyone without a regular specialist or primary care relationship, that continuity is the practical difference between a result and a cure.
Providence tests for hepatitis B, hepatitis C, and TB in addition to gonorrhea, chlamydia, syphilis, and HIV. A panel that serves anyone whose exposure history or clinical picture goes beyond what a basic sexual-health screen covers. People managing chronic liver disease risk, needle-sharing history, or immigration health requirements will find the relevant tests in one appointment.

Snohomish County Health Department in Everett runs appointments-only visits that cover rapid and conventional HIV, hepatitis C, syphilis, gonorrhea, and chlamydia testing alongside STI treatment and DoxyPEP. With every service provided at no fee, on a sliding scale for all.
Snohomish County Health Department carries the full testing and treatment slate, bacterial STI treatment included, at no charge for every patient. For anyone navigating care without a primary provider or paying entirely out of pocket, that means nothing is gated behind a bill at the end of the visit.
Spanish-speaking patients can work through their visit, questions, and counseling directly in Spanish, and interpretation services extend that access to other languages as well. For someone whose clearest thinking happens outside of English, the conversation doesn't lose anything in translation.
Snohomish County Health Department prescribes DoxyPEP, the post-exposure antibiotic regimen that reduces bacterial STI acquisition, directly at the clinic, which means a patient who qualifies can leave with the medication rather than chasing a separate prescription.

STD stats & rates
How reported STI rates in Snohomish County, the county that includes Hat Island, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data.
#24 of 39 Washington counties for chlamydia, a higher rate than 38% of the state
| Infection | Snohomish County | Washington | United States |
|---|---|---|---|
| Chlamydia | 252.7 2,135 cases ▼ 29% | 354.4 | 492.2 |
| Gonorrhea | 74.7 631 cases ▼ 42% | 129.6 | 179.5 |
| Syphilis (P&S) | 8 68 cases ▼ 62% | 21.3 | 15.8 |
| Syphilis (early) | 8.2 69 cases ▼ 34% | 12.5 | 16 |
| Syphilis (late/unknown) | 10.7 90 cases ▼ 53% | 22.9 | 29.5 |
Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Snohomish County, chlamydia has fallen from 321.6 to 252.7 per 100,000 (21%), gonorrhea has fallen from 98 to 74.7 per 100,000 (24%), and P&S syphilis has risen from 7.5 to 8 per 100,000 (7%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Snohomish County.
Local HIV snapshot
Snohomish County HIV care continuum (2023)
Snohomish County recorded 3.8 new HIV diagnoses per 100,000 (2023), against 6.3 statewide and 13.7 nationally. Among Snohomish County residents living with HIV, 85.2% are in care · 77.9% 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 Snohomish County tests for syphilis.

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.
