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

Rated 3 out of 5 from 5 reviews

Idaho North Central District Health Department in Lewiston tests for gonorrhea, chlamydia, syphilis, herpes, and HIV on a sliding scale open to everyone, with insurance and Medicaid accepted, and every service carries no fee at point of care. Appointments are required; bacterial STIs are treated the same visit.

Zero-Fee Services Across the Full Visit

Idaho North Central District Health Department charges nothing for any service it provides: testing, treatment, vaccination, and prevention counseling alike. That blanket applies regardless of insurance status, meaning the sliding scale functions as a ceiling of zero rather than a reduced figure.

Spanish-Language Care Fully on Staff

Spanish is one of the clinic's operating languages, placing it among a narrow set of public health departments where clinical conversations (exposure history, treatment instructions, follow-up planning) happen directly in both English and Spanish. That capacity shapes what a visit can accomplish for speakers of either language.

DoxyPEP Prescribed for the Right Candidates

Idaho North Central District Health Department prescribes DoxyPEP, doxycycline taken after potential bacterial STI exposure, for people whose exposure patterns make it a fit. The clinic's standing capability to evaluate, prescribe, and counsel on DoxyPEP is particularly consequential for anyone without a regular provider who might otherwise have no clear path to this prevention option.

Rated 3.5 out of 5 from 62 reviews

CHAS Health, a federally qualified community health center in Lewiston, weaves STI care into the same clinical infrastructure that handles primary and preventive medicine: meaning gonorrhea, chlamydia, syphilis, and HIV testing, same-visit bacterial treatment, and sliding-scale fees all live alongside full ongoing care, with appointments required, and Russian spoken on staff.

Read full overview Show less

Russian Spoken by Clinical Staff Here

Without a Russian-speaking clinician, a patient navigating an STI diagnosis faces follow-up appointments that don't happen, treatment instructions that don't land, and gaps that quietly compound. At CHAS Health in Lewiston, Russian is a staff language: meaning the clinical conversation, the treatment plan, and the follow-up all happen in it.

PrEP Prescribed and Monitored On-Site

Tenofovir-based PrEP requires regular HIV testing, kidney-function monitoring, and prescription renewals. The infrastructure that actually keeps someone protected long-term. CHAS Health in Lewiston carries all of that within its primary-care system, so PrEP isn't handed off; it's sustained.

Hepatitis C Treatment Completed Here

For someone without a specialist relationship or managing costs on a sliding scale, hepatitis C treatment that requires a separate referral is treatment that often doesn't happen. CHAS Health in Lewiston holds both the diagnosis and the curative antiviral treatment on-site, so a confirmed hep C result moves directly into a treatment plan.

Rated 3.8 out of 5 from 45 reviews

Planned Parenthood of Greater Washington and North Idaho in Pullman runs on a sliding scale with Medicaid and private insurance accepted, covering gonorrhea, chlamydia, syphilis, herpes, and rapid HIV testing: same-visit bacterial treatment included, by appointment, with Spanish and interpretation services on hand.

Read full overview Show less

Spanish and Interpretation Built Into Every Appointment

Planned Parenthood of Greater Washington and North Idaho in Pullman staffs Spanish-language care and interpretation services as a standing clinical resource, not a scheduling add-on. For anyone navigating STI care, prevention counseling, or PrEP in a language other than English, that capability means the full conversation happens at full depth, first visit.

Title X Means Minors Don't Wait on a Parent's Consent

Without Title X, a minor needing STI testing or family planning often hits a consent wall: care delayed, a condition untreated, or a second appointment that never happens. At Planned Parenthood of Greater Washington and North Idaho in Pullman, Title X funding legally guarantees confidential services for minors, so that gap doesn't open.

PrEP, PEP, and DoxyPEP Prescribed at This Location

DoxyPEP, doxycycline taken after a potential bacterial STI exposure, is prescribed directly at Planned Parenthood of Greater Washington and North Idaho in Pullman, alongside daily PrEP and PEP for HIV prevention. Having all three under one prescribing relationship means dosing, monitoring, and adjustments stay coordinated rather than scattered across providers.

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.

Congenital syphilis is the fastest-rising STI: what to test, and when

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 Asotin County tests for syphilis.

Local context

About Clarkston, WA

Clarkston sits almost evenly between owners and renters, a near-even split that says something about who's managing budgets tightly here. For the renting half of the city, typical monthly costs leave little slack, and when unemployment runs noticeably high, discretionary spending, including healthcare visits that feel optional, gets deferred first. That pressure matters when you consider that younger adults still forming relationships represent a substantial share of Clarkston's population, precisely the years when routine STI screening has the greatest impact and is most easily skipped. Getting tested in Clarkston also means contending with the geography.

With labor-force participation below national norms and irregular employment common, scheduling around clinic hours is a real logistical puzzle, not a minor inconvenience. The options listed on this page exist specifically to widen that window. Average households here run larger than the national norm, which means many people are balancing shared finances and shared schedules. A reality that makes low-cost, efficient appointments more than a convenience.

Asotin County's STI picture reinforces the case for screening that's affordable enough to be repeatable, not a once-in-a-while event prompted only by symptoms. The clinics along this corridor are the practical answer to that need.

What each STD test costs

Medicare reference prices per lab test, a benchmark before you pay out of pocket

Public clinics and the community health centers serving Clarkston often test free or on a sliding scale; private labs and at-home kits bundle several tests into one fee. Use this as a per-test benchmark before you pay out of pocket, or see the full guide to STD test costs for insurance, free, and at-home options.

Confidentiality & consent in Washington

Minor consent and partner treatment (EPT) under state law, plus how to test privately

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).

Can a minor consent on their own?

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

Can my partner be treated too? (EPT)

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.
