See your options below.
Available testing centers
4 testing options are listed for Keystone, SD. The nearest, Monument Health Network, is about 7.8 miles away. Compare community and public clinics, private labs, and at-home kits below.
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.

A public safety-net rural health clinic about 8 miles from Keystone. Sliding-scale STD testing and care are typical here, call ahead to confirm the exact panel and pricing.
Tests offered
Oyate Health Center in Rapid City covers gonorrhea, chlamydia, syphilis, herpes, and conventional HIV testing, treating bacterial infections the same visit and carrying hepatitis A and B vaccines. Every service at no fee, by appointment.
Sliding-scale fees still leave a balance at most clinics, a number patients quietly absorb or avoid. At Oyate Health Center, every service, test, vaccine, and treatment carries no charge at all. That's not a program with eligibility criteria; it's simply how the clinic operates.
When a clinic can't deliver STI care in Spanish, a patient leaves with partial information, a follow-up appointment somewhere else, or nothing acted on. Oyate Health Center delivers testing, treatment, counseling, and prevention education directly in Spanish. No gap between the visit and full understanding of results.
The typical STI clinic panels for gonorrhea, chlamydia, syphilis, and HIV, and herpes falls off the list. Oyate Health Center tests for all four and adds herpes, so a single appointment captures infections that often go undetected simply because no one ordered the test.

STD stats & rates
How reported STI rates in Pennington County, the county that includes Keystone, compare with South Dakota 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.
#13 of 66 South Dakota counties for chlamydia, a higher rate than 80% of the state
| Infection | Pennington County | South Dakota | United States |
|---|---|---|---|
| Chlamydia | 672.1 779 cases ▲ 26% | 531.6 | 492.2 |
| Gonorrhea | 429.7 498 cases ▲ 70% | 253.3 | 179.5 |
| Syphilis (P&S) | 126.8 147 cases ▲ 73% | 73.4 | 15.8 |
| Syphilis (early) | 126 146 cases ▲ 64% | 76.8 | 16 |
| Syphilis (late/unknown) | 76.8 89 cases ▲ 5% | 72.9 | 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 Pennington County, chlamydia has risen from 637.2 to 672.1 per 100,000 (5%), gonorrhea has fallen from 500.8 to 429.7 per 100,000 (14%), and P&S syphilis has risen from 19.2 to 126.8 per 100,000 (560%).

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 Pennington County.
Local HIV snapshot
Pennington County HIV care continuum (2022)
Pennington County recorded 8.3 new HIV diagnoses per 100,000 (2022), against 6.8 statewide and 13.7 nationally. Among Pennington County residents living with HIV, 92% are in care · 84% 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 Pennington County tests for syphilis.

Data & references
Local context
Keystone earned its name as the gateway to Mount Rushmore, and that threshold identity still shapes the town. A place where visitors arrive seeking one landmark and locals build lives in its shadow. That mix of transience and rootedness means health needs here don't fit a single profile. Young adults make up a visible part of the community, and for them STI testing carries particular weight during years when sexual health decisions happen quietly, away from the eye of neighbors or colleagues who might recognize a face in a waiting room. Testing in and around Keystone is available through providers listed on this page, and the confidentiality protocols matter here as much as anywhere.
A test result stays between you and the clinic: no automatic word spreads, no notification to employers or family. That separation between your health record and your daily life in a recognizable town is real and protected by law. The Keystone Historical Museum sits a short walk from where you might seek care, a reminder that this town's identity has always been layered: a place shaped by what draws people in, and equally by what keeps residents grounded. That same layering applies to sexual health: routine screening is available without fanfare, and getting tested fits seamlessly into the ordinary care that adults pursue at their own pace.
Getting there
At 6.11/20 on the EPA walkability index, day-to-day errands in Keystone generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Two things that actually depend on South Dakota 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 South Dakota, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Expedited Partner Therapy (EPT) is potentially allowable in South Dakota: it is not expressly authorized, but not prohibited either. Ask your provider whether they will prescribe treatment for a partner without a separate visit.
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.
