STD testing near Colfax, WA

9 testing options are listed for Colfax, WA. The nearest, Planned Parenthood of Greater Washington and North Idaho, is about 15.0 miles away. Compare 5 community and public clinics, private labs, and at-home kits below.

How to read these listings

Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

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.

Rated 4.4 out of 5 from 95 reviews

WISH Medical in Moscow runs appointments-only STI care covering HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B, and hepatitis C, with same-visit treatment for bacterial infections, and charges nothing for any of it, on a sliding scale that reaches zero.

Read full overview Show less

Every Test, Every Visit, No Charge

When cost becomes the reason someone delays a test or skips a follow-up, an untreated infection advances. WISH Medical charges nothing (no fee for any test, no fee for any service) so that barrier never gets the chance to create a gap in care.

Language Access Built Into Every Appointment

Without interpretation, a diagnosis lands without context and a treatment plan without clarity. Both of which can mean instructions that don't get followed. WISH Medical provides interpretation services for non-English languages directly within appointments, so the clinical conversation is complete from the start.

Herpes and Hepatitis Testing Alongside the Standard Four

Someone without a regular provider who needs a thorough baseline (not just gonorrhea, chlamydia, syphilis, and HIV) finds WISH Medical's panel covers herpes, hepatitis B, and hepatitis C as well, all in a single scheduled visit and at no cost.

Rated 3.4 out of 5 from 81 reviews

CHAS Health in Moscow covers gonorrhea, chlamydia, syphilis, conventional HIV, and hepatitis C testing, treating bacterial infections the same visit they're found. Fees run on a sliding scale with Medicaid, Medicare, and insurance all accepted; an appointment is required.

Read full overview Show less

PrEP and PEP Are Both on the Menu

CHAS Health prescribes both PrEP for ongoing HIV prevention and PEP when prevention is needed after the fact. Having both available through the same clinic means your prevention plan can shift as your circumstances do, without switching providers.

Hepatitis C Managed From Diagnosis Through Treatment

For someone paying out of pocket or without a specialist on their care team, CHAS Health's capacity to treat hepatitis C on-site is the difference between a diagnosis that leads somewhere and one that stalls. The clinic carries both the testing and the follow-through, so the path from detection to treatment stays in one place.

Hepatitis Testing Fills the Gap Most Panels Leave

Standard STI panels at many clinics cover the bacterial infections and HIV, then stop. CHAS Health folds hepatitis C into the same visit, catching an infection that circulates alongside the others but rarely makes it onto a basic order.

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 Whitman County tests for syphilis.

Local context

About Colfax, WA

Getting tested for STIs in Colfax means planning ahead. The town itself has limited testing infrastructure, so many residents travel to nearby Pullman or Spokane for clinic visits. A reality that shapes how people approach their health care. That distance, combined with modest living costs that leave tight budgets for some, can make the choice to seek screening feel more deliberate than it might elsewhere.

The testing services listed on this page reflect what's available in and around Colfax, including options beyond the immediate area for those willing to make the drive. Young adults who've recently moved to Colfax or grown up here often find themselves at the stage of life when routine confidential screening becomes relevant: whether they're establishing themselves in a job, settling into a relationship, or simply taking stock of their health. The practical isolation of a smaller town can actually clarify priorities: you know what you need, you know where to find it, and you're more likely to follow through without the distraction of endless local choices. Testing remains confidential regardless of where you go, and results don't ripple back into town gossip.

The clinics and providers accessible from Colfax understand that people seek care for straightforward reasons, and they treat screening as routine medical business. Nothing more, nothing less.

What each STD test costs

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

These are the federal Medicare reference prices for processing each lab test. Public clinics and the community health centers serving Colfax 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.
