A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Yakima Valley Farm Workers Clinic in Toppenish is a community health center where STI testing (gonorrhea, chlamydia, syphilis, herpes, HIV, and hepatitis A, B, and C) runs on a sliding-scale fee open to everyone, with appointments required and same-visit treatment available for bacterial infections.
Plenty of clinics route non-English conversations through an external line, adding friction at exactly the wrong moment. Yakima Valley Farm Workers Clinic carries both Spanish-speaking staff and broader interpretation services directly into the exam room, so the clinical conversation happens in full. Not filtered.
Without a regular primary care provider, getting herpes and hepatitis A, B, and C tested in the same visit as gonorrhea, chlamydia, syphilis, and HIV can be genuinely difficult to arrange. Yakima Valley Farm Workers Clinic carries all of them, so a single appointment builds a complete picture rather than a partial one.

The no-fee structure at Indian Health Service isn't limited to a single program or test type: it runs through every service the clinic provides, including treatment, vaccines, and counseling, staffed and billed so that nothing is unbundled into a separate charge when you leave.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Indian Health Service tests for herpes and hepatitis A, B, and C in the same visit, which means infections that often go undetected elsewhere get identified early enough to act on, including same-visit treatment for bacterial STIs.

The clinic tests for hepatitis A, B, and C alongside gonorrhea, chlamydia, syphilis, and HIV, so a single visit produces a more complete picture of liver-affecting infections. Useful given that hepatitis B and C can go undetected without a targeted test.

STD stats & rates
How reported STI rates in Yakima County, the county that includes Zillah, compare with Washington 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.
#2 of 39 Washington counties for chlamydia, among the very highest in the state
| Infection | Yakima County | Washington | United States |
|---|---|---|---|
| Chlamydia | 743.1 1,907 cases ▲ 110% | 354.4 | 492.2 |
| Gonorrhea | 141.1 362 cases ▲ 9% | 129.6 | 179.5 |
| Syphilis (P&S) | 51.4 132 cases ▲ 141% | 21.3 | 15.8 |
| Syphilis (early) | 32.3 83 cases ▲ 158% | 12.5 | 16 |
| Syphilis (late/unknown) | 54.6 140 cases ▲ 138% | 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 Yakima County, chlamydia has risen from 638.8 to 743.1 per 100,000 (16%), gonorrhea has fallen from 231.8 to 141.1 per 100,000 (39%), and P&S syphilis has risen from 8.2 to 51.4 per 100,000 (527%).

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 Yakima County.
Local HIV snapshot
Yakima County HIV care continuum (2023)
Yakima County recorded 8.3 new HIV diagnoses per 100,000 (2023), against 6.3 statewide and 13.7 nationally. Among Yakima County residents living with HIV, 87.8% are in care · 79.4% 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 Yakima County tests for syphilis.

Data & references
Local context
Teapot Dome Gas Station sits along WA 22 like a landmark that's barely changed in decades, and that settled quality runs through much of Zillah, where most households own their homes and families tend to be larger than the state average. That rootedness shapes daily life here, but it doesn't simplify the logistics of getting tested: the options listed on this page require a drive out along the Evergreen Highway or toward Toppenish, and for the roughly six in ten adults outside the labor force, or anyone working shifts that leave little room for a mid-week appointment, scheduling around clinic hours takes real planning.
Zillah's young adults, people in their late teens and twenties forming relationships and moving between jobs, are the group most likely to benefit from routine STI screening, and Yakima County's rates give that urgency local weight. With average households running closer to three and a half people, a positive result that goes undetected affects more than one person's health.
The cost picture is specific here. Rent around $921 a month is not negligible against the area's income landscape, and with fewer than a quarter of households clearing six figures, out-of-pocket fees matter. The clinics listed on this page vary in sliding-scale availability and uninsured pricing, details worth checking before the drive rather than after arriving.
Getting there
At 3.17/20 on the EPA walkability index, day-to-day errands in Zillah 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 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.
