Washington, Washington County reports syphilis cases about 73% lower than the US average, but getting tested in Marine on St. Croix, Minnesota before starting a new relationship or as part of ongoing care is important. Clinics may bill insurance or offer sliding-scale fees, while many private labs let you pay a flat self-pay price.
Available testing centers
7 testing options are listed for Marine on St. Croix, MN. The nearest, Allina Health, is about 11.0 miles away. Compare community and public clinics, private labs, and at-home kits below.
Allina Health Columbus runs on scheduled appointments, so a single planned visit covers gonorrhea, chlamydia, syphilis, and conventional HIV testing alongside HPV, hepatitis A, and hepatitis B vaccines: with fees billed to insurance, Medicaid, or Medicare, and same-visit treatment for bacterial infections. Spanish is spoken on staff.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Allina Health Columbus tests for herpes simplex, hepatitis A, and hepatitis B in the same appointment. Conditions whose clinical management diverges sharply from bacterial STIs and that require their own laboratory workup to confirm.
Substance-use treatment at Allina Health Columbus is a bookable clinical service, not a separate referral chain. Meaning a patient managing both a substance-use condition and an STI diagnosis can schedule coordinated care within the same facility, keeping treatment timelines linked rather than parallel.
Allina Health Columbus delivers care directly in Spanish, which means sexual-health history, symptom detail, and treatment instructions are exchanged with clinical staff in the same language. Reducing the compression that comes when nuance has to travel through an intermediary.

Entira Family Clinics in Hugo tests for HIV, gonorrhea, chlamydia, syphilis, herpes, hepatitis A, B, and C, and TB, with same-visit treatment for bacterial STIs on a sliding-scale fee structure, and conducts care in American Sign Language, Chinese, French, and Haitian Creole.
Deaf patients and those whose primary language is Chinese, French, or Haitian Creole can have every clinical conversation (history, results, counseling) conducted directly in that language by staff, without relay services mediating the exchange. That standing capability shapes who can realistically use this clinic as their regular STI care provider.
Entira prescribes and manages both PrEP, typically daily oral tenofovir-based regimens, and PEP within its own clinical staff, meaning the prescribing, follow-up lab monitoring, and adherence counseling all run through the same appointment structure rather than requiring a separate specialist relationship.
Diagnosis alone leaves patients to navigate treatment elsewhere, a gap that often stalls care entirely. Entira Family Clinics in Hugo closes that gap by carrying hepatitis C treatment on-site alongside hepatitis B treatment, so a confirmed diagnosis leads directly to a treatment plan within the same practice.

STD stats & rates
How reported STI rates in Washington County, the county that includes Marine on St. Croix, compare with Minnesota and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~12% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#38 of 87 Minnesota counties for chlamydia, a higher rate than 56% of the state
| Infection | Washington County | Minnesota | United States |
|---|---|---|---|
| Chlamydia | 226.2 631 cases ▼ 40% | 379.5 | 492.2 |
| Gonorrhea | 59.5 166 cases ▼ 56% | 134.5 | 179.5 |
| Syphilis (P&S) | 4.3 12 cases ▼ 51% | 8.7 | 15.8 |
| Syphilis (early) | 1.4 4 cases ▼ 79% | 6.7 | 16 |

Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Washington County, chlamydia has fallen from 248.5 to 226.2 per 100,000 (9%), gonorrhea has fallen from 94.9 to 59.5 per 100,000 (37%), and P&S syphilis has risen from 3.4 to 4.3 per 100,000 (26%).

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 Washington County.
Local HIV snapshot
Washington County HIV care continuum (2023)
Washington County recorded 2.6 new HIV diagnoses per 100,000 (2023), against 6.7 statewide and 13.7 nationally. Among Washington County residents living with HIV, 82.1% are in care · 62.3% 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 Washington County tests for syphilis.

Data & references
Local context
The St. Croix River drew settlers to this bend in the landscape centuries ago, and the town that took root there still holds that water-centered identity. Today, STI testing in Marine On St. Croix reflects the same practicality that built the community, straightforward access to screening without unnecessary barriers.
The clinics and urgent care facilities listed on this page serve residents and those passing through with the same directness the river itself demands. Young adults in their late teens through early thirties make up a meaningful presence here, a group for whom confidential, routine testing fits naturally into responsible health habits. Testing appointments can happen quickly, and what you discuss with a provider stays with that provider. The absence of automatic notification to anyone else is standard practice, not an exception granted on request.
Burris Park and the artist studios along the riverfront speak to a town that values both tradition and openness. That same character extends to sexual health: screening is destigmatized, accessible, and treated as ordinary preventive care. Whether you live here year-round or are new to the area, the testing services available in and around Marine On St. Croix are designed to be as straightforward as the community itself.
Getting there

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