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.

Oregon Health and Science University in Scappoose runs by appointment, so arriving with a scheduled slot means the full panel (gonorrhea, chlamydia, syphilis, herpes, hepatitis B and C, and rapid or conventional HIV) gets handled in one visit, with same-visit treatment for bacterial infections and sliding-scale fees for all.
A hepatitis C diagnosis that sends you to a separate specialist means a second intake, a longer wait, and a gap where the infection keeps advancing. At Oregon Health and Science University in Scappoose, the treatment follows the diagnosis without leaving the building, so the clock on managing the infection doesn't stall between two separate care relationships.
Oregon Health and Science University in Scappoose prescribes PrEP and PEP directly, which means the follow-up lab work and adherence support that make prevention medication actually work are built into the same clinical relationship rather than scattered across separate providers.
Many clinics can schedule in Spanish but revert to interpreted exchanges once care begins. Oregon Health and Science University in Scappoose delivers care in Spanish through the clinical encounter itself: the kind of continuity where a patient can name a symptom, ask a follow-up, or weigh a treatment option in the language they reason in.

Sea Mar Community Health Centers in Vancouver runs STI testing and treatment through its full community health infrastructure: appointments required, sliding-scale fees for everyone, with same-visit treatment for bacterial infections like gonorrhea, chlamydia, and syphilis, and all services provided at no fee.
Sea Mar's testing roster goes beyond gonorrhea, chlamydia, syphilis, and HIV to include hepatitis B and hepatitis C. Both run through the clinic's own lab infrastructure. Hepatitis C treatment, when indicated, is managed on-site rather than handed off elsewhere, keeping monitoring and follow-up within the same clinical team.
Spanish-language care at Sea Mar is delivered by staff who conduct intake, counseling, and clinical conversations directly in Spanish. It's embedded in how the clinic is hired and scheduled, not routed through an external service. That means HIV test counseling, prevention education, and STI treatment discussions all happen in Spanish with the same provider.
Sea Mar structures its fees so that the full scope of services (testing, treatment, vaccines including Mpox and HPV, and HIV/AIDS medical management) is available at no charge. The clinic accepts Medicaid and Medicare and applies a sliding scale, with the operational result that no service line within the visit generates a balance.

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 Columbia County, the county that includes St. Helens, compare with Oregon 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.
#13 of 36 Oregon counties for chlamydia, a higher rate than 64% of the state
| Infection | Columbia County | Oregon | United States |
|---|---|---|---|
| Chlamydia | 291.4 157 cases ▼ 20% | 362.5 | 492.2 |
| Gonorrhea | 53.8 29 cases ▼ 54% | 117.2 | 179.5 |
| Syphilis (P&S) | 24.1 13 cases ▲ 26% | 19.2 | 15.8 |
| Syphilis (early) | 3.7 2 cases ▼ 61% | 9.6 | 16 |
| Syphilis (late/unknown) | 5.6 3 cases ▼ 72% | 19.7 | 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 Columbia County, chlamydia has fallen from 308 to 291.4 per 100,000 (5%), gonorrhea has fallen from 57 to 53.8 per 100,000 (6%), and P&S syphilis has risen from 1.9 to 24.1 per 100,000 (1168%).

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 Columbia County.
Local HIV snapshot
Columbia County HIV care continuum (2020)
Columbia County recorded 0 new HIV diagnoses per 100,000 (2020), against 6.6 statewide and 13.7 nationally. Among Columbia County residents living with HIV, 87.3% are in care · 78.2% 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 Columbia County tests for syphilis.

Data & references
Local context
St. Helens Downtown Historic District sits along the Columbia waterfront with the kind of unhurried character that makes the town feel more rooted than its size suggests. Most households here are owner-occupied, with multigenerational or family-sized arrangements common enough that the average home holds just over three people. That domestic stability is real, but it coexists with a labor market where a meaningful share of working-age residents are outside the workforce entirely, and nearly one in four who are looking aren't finding work. For people carrying a modest rent on a tight budget, an extra trip up US 30 to reach a testing site can feel like a genuine calculation, not a minor errand.
That calculation matters most for the younger adults in St. Helens, people in their late teens and twenties forming relationships and moving between rentals in areas like West Saint Helens or closer to the Houlton Business District. Columbia County's STI rates carry the patterns typical of the Pacific Northwest's smaller river towns: chlamydia and gonorrhea concentrated in exactly those years when scheduling a clinical visit tends to fall behind rent, work shifts, and transport.
With only about one in five households clearing six figures, sliding-scale fees at the options listed here are worth understanding before booking. Some sites on this page accept Medicaid and Oregon Health Plan coverage, which can bring the out-of-pocket cost for a standard panel down to nothing, a detail especially relevant for renters at that $901 median monthly threshold.

Two things that actually depend on Oregon 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 Oregon, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Oregon 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.
