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

Columbia Health Services in Saint Helens runs on a sliding scale accepted by Medicaid, Medicare, and most private insurers, covering gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis B, hepatitis C, and TB. With same-visit treatment for bacterial infections and appointments required. Spanish and interpretation services are on staff.
Columbia Health Services maintains Spanish-language capacity and interpretation services as a staffed clinical resource: meaning providers can conduct full history-taking, counseling, and treatment discussions directly, without routing through an outside service mid-appointment. The operational result is a visit that moves at the same pace regardless of the language spoken.
Plenty of testing sites hand back results without any mechanism to initiate HIV prevention medication. Columbia Health Services prescribes and manages both PrEP and PEP on-site, meaning the clinic can move from a reactive test to an active prevention plan within the same care relationship, not across separate providers.
Beyond the four-infection baseline, Columbia Health Services tests for herpes, hepatitis B, and hepatitis C. Each requiring its own distinct specimen type and lab protocol. Hepatitis C is handled with on-site treatment rather than an outside referral, and hepatitis B vaccination is available to close the loop on a reactive or negative result.

Sea Mar Community Health Centers in Battle Ground runs testing by appointment, and a single visit covers gonorrhea, chlamydia, syphilis, HIV, hepatitis A, B, and C, and TB: with same-visit treatment for bacterial infections, sliding-scale fees, and care delivered in Spanish.
Plenty of clinics field Spanish-speaking patients with workarounds that keep the conversation at arm's length. At Sea Mar Community Health Centers in Battle Ground, Spanish is a primary language of care. The kind of fluency where clinical nuance and follow-up questions land the way they're meant to.
Getting diagnosed with hepatitis C and then waiting months for a specialist to clear the actual infection is a gap where treatment stalls and transmission risk lingers. Sea Mar Community Health Centers in Battle Ground carries hepatitis C treatment on-site, so a confirmed diagnosis moves directly into a managed care plan without an intervening referral chain.
Leaving hepatitis off a routine STI screen means a separate appointment, a separate lab order, and often a gap of weeks before those results inform any care decision. Sea Mar Community Health Centers in Battle Ground tests for hepatitis A, B, and C alongside gonorrhea, chlamydia, syphilis, and HIV, so the full picture is available from a single visit.

ZoomCare in Vancouver charges on a fee basis with insurance accepted, covering gonorrhea, chlamydia, syphilis, HIV, herpes, and all three hepatitis strains. Appointments are required, bacterial STIs are treated same visit, and HPV and hepatitis A and B vaccines are available.
ZoomCare carries both PrEP and PEP as standing services, which means someone without an established primary care provider, or one who prefers to consolidate sexual health management in one place, can access either medication directly here rather than tracking down a separate prescriber.
ZoomCare tests for herpes and all three hepatitis strains in addition to the standard gonorrhea, chlamydia, syphilis, and HIV panel, which means a single visit can surface infections that a narrower screen would leave undetected and unaddressed.

STD stats & rates
How reported STI rates in Clark County, the county that includes La Center, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~29% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#14 of 39 Washington counties for chlamydia, a higher rate than 64% of the state
| Infection | Clark County | Washington | United States |
|---|---|---|---|
| Chlamydia | 346 1,803 cases ▼ 2% | 354.4 | 492.2 |
| Gonorrhea | 98.6 514 cases ▼ 24% | 129.6 | 179.5 |
| Syphilis (P&S) | 18 94 cases ▼ 15% | 21.3 | 15.8 |
| Syphilis (early) | 4.6 24 cases ▼ 63% | 12.5 | 16 |

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 Clark County, chlamydia has fallen from 371.1 to 346 per 100,000 (7%), gonorrhea has fallen from 136.1 to 98.6 per 100,000 (28%), and P&S syphilis has risen from 12.3 to 18 per 100,000 (46%).

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 Clark County.
Local HIV snapshot
Clark County HIV care continuum (2023)
Clark County recorded 5 new HIV diagnoses per 100,000 (2023), against 6.3 statewide and 13.7 nationally. Among Clark County residents living with HIV, 85.4% 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 Clark County tests for syphilis.

Local resources & officials
Data & references
Local context
Northwest La Center Road cuts through a town where most households own their homes and have done so long enough to feel settled, yet that stability coexists with a cost structure that leaves little slack. Typical rent runs well above regional averages for a small Clark County community, and nearly half of all households clear six figures, which means the people who don't are navigating a noticeably expensive place on tighter margins. Larger-than-average household sizes and a strong majority of married adults point to a community oriented around families, which shapes everything from how time gets allocated to how health decisions get made. Often quietly, around everyone else's schedule.
That scheduling reality matters most for younger adults, the late-teens-and-twenties crowd who see the highest rates of new STI diagnoses and who are also, in a community like this, often balancing work with commutes out toward Vancouver or beyond. Some a real drive from West Pioneer or Ridgefield Junction, worth knowing before you need one. Clark County's STI trends don't pause for a quiet stretch of Northwest Pacific Highway, and neither does the calendar.

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.
