Terry Reilly Health Services in Marsing runs appointments for gonorrhea, chlamydia, syphilis, and hepatitis C testing, treating confirmed bacterial infections the same visit; fees follow a sliding scale accepted alongside Medicaid, Medicare, and private insurance.
When a hepatitis C antibody comes back reactive, the follow-up (confirmatory RNA testing, genotyping, and direct-acting antiviral prescribing) is handled by Terry Reilly's own clinical staff, with monitoring built into ongoing appointments at the same Marsing location.
Terry Reilly orders hepatitis C serology alongside gonorrhea, chlamydia, syphilis, and HIV, meaning a single appointment generates results across both the bacterial and viral spectrum. One care team reading the full picture rather than separate referrals for each infection category.

Southwest District Health in Caldwell offers free HIV and STI testing across a full panel (gonorrhea, chlamydia, syphilis, herpes, hepatitis A, B, and C, TB, and rapid or conventional HIV) with sliding-scale fees on other services, Medicaid and insurance accepted, and same-visit treatment for bacterial infections by appointment.
Southwest District Health's no-fee structure extends well beyond the test itself: STI treatment, HIV/AIDS medical care, PrEP, PEP, and vaccines all carry no charge. For anyone managing a condition without a regular provider or paying entirely out of pocket, that coverage across the full scope of care removes a series of separate financial decisions.
Many clinics offer language access only through an external service that arrives late or drops off mid-appointment. Southwest District Health provides Spanish-speaking staff and interpretation services directly, so the conversation about symptoms, medication, or follow-up happens in real time, with the provider in the room.
Southwest District Health prescribes and manages both PrEP, including Truvada and Descovy, and PEP directly, with no-cost access available for uninsured patients on PrEP. Ongoing HIV medical treatment is also handled here, meaning the full arc from prevention medication through HIV care stays with a single clinical team.

STD stats & rates
How reported STI rates in Owyhee County, the county that includes Marsing, compare with Idaho and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~19% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#29 of 44 Idaho counties for chlamydia, a higher rate than 34% of the state
| Infection | Owyhee County | Idaho | United States |
|---|---|---|---|
| Chlamydia | 165.1 21 cases ▼ 44% | 294.9 | 492.2 |
| Gonorrhea | 31.4 4 cases ▼ 21% | 39.6 | 179.5 |
| Syphilis (P&S) | 7.9 1 cases ▲ 108% | 3.8 | 15.8 |
| Syphilis (early) | — no data | 3.1 | 16 |
| Syphilis (late/unknown) | 23.6 3 cases ▲ 275% | 6.3 | 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 Owyhee County, chlamydia has fallen from 428.1 to 165.1 per 100,000 (61%), gonorrhea has fallen from 109.1 to 31.4 per 100,000 (71%), and P&S syphilis has fallen from 8.4 to 7.9 per 100,000 (6%).

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 Owyhee County.
Local HIV snapshot
Owyhee County HIV care continuum (2023)
Owyhee County recorded 0 new HIV diagnoses per 100,000 (2023), against 3 statewide and 13.7 nationally. 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 Owyhee County tests for syphilis.

Data & references
Local context
ID-55 through Marsing runs straight and flat, West Main Street into East Main Street into Sunnyslope Road, and the nearest testing option listed on this page means a real drive out of town, not a walk across a parking lot. That distance lands differently when most households here own their homes and have put down roots, but a third of residents rent at rates well below the state average, leaving little financial cushion for anything that feels optional until it suddenly isn't. Marsing's households run large, and nearly half of adults are married. Meaning sexual health decisions ripple outward to partners and families, not just individuals.
The share of residents in their late teens and twenties is smaller than in many Idaho cities, but people in that life stage face the steepest screening gaps nationally, and a round trip on ID-55 to the nearest clinic is the kind of errand that gets weighed against work shifts and childcare in a community where labor-force participation is solid but high-earning households are rare. The options listed on this page include lower-cost and sliding-scale sites worth comparing before committing to a specific appointment. For a town where most people know their neighbors and households average more than three people, routine screening is less a personal calculation than a household one.
Getting there
At 5.23/20 on the EPA walkability index, day-to-day errands in Marsing generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
Two things that actually depend on Idaho 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 Idaho, a minor aged 14 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
Idaho 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.
