Herpes and Hepatitis Tested Here, Not Later
Leaving herpes or hepatitis untested means a separate appointment elsewhere, another fee, another wait, another chance the result never gets acted on. Horizon Health Care's panel covers herpes alongside hepatitis A, B, and C, so a single visit to Howard closes those gaps rather than deferring them.
Your Language at the Appointment, Not After
Without on-site interpretation, a missed nuance in a test explanation or a treatment instruction becomes a real clinical risk. Not an inconvenience. Horizon Health Care in Howard has interpretation services available for non-English languages, keeping every part of your care accurate from the conversation forward.
Beyond the dedicated testing centers above: at-home kits by mail, hospital labs certified for STI testing, local clinicians who can order a panel during a regular visit, pharmacies for self-test kits and prescriptions, and online PrEP & treatment.
The nearest testing center is about 14 miles away; if you'd rather skip the trip, an at-home kit ships to Carthage, you collect the sample privately, and mail it back to a CLIA-certified lab. Results come online in days, with a clinician available if anything is positive. Same labs as a clinic, no waiting room, and you can read how accurate at-home STD tests are before you order.
Want a free option first? The CDC-supported TakeMeHome (opens in a new tab) program mails free at-home HIV self-test kits, and, in many areas, free STI kits, to your door, with no insurance or payment needed. The paid kits below add broader panels and faster turnaround.

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.

Pregnant or planning to be?
Congenital syphilis is the fastest-rising STI: what to test, and when
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 Miner County tests for syphilis.

Carthage runs on a workforce that skews toward stay-at-home households and part-time schedules, barely half of adults are in the labor force at any given time, which sounds like flexibility but rarely translates that way. The people who are working often piece together hours across shifts, and the roughly three in ten residents who rent here are doing it on modest budgets that leave little room for clinic costs that feel optional. For younger adults still sorting out relationships and sexual health habits, that cost hesitation is real: when rent is already a stretch, an out-of-pocket screening can feel like a line item to delay rather than a Tuesday errand. Getting there is its own calculation.
That logistical weight lands hardest on the people who most benefit from routine screening: adults in their late teens and twenties, whose STI rates run highest precisely because they're in the years of new partners and shifting circumstances. The good news is that with the local options on this page, the comparison work is already done. Hours, fees, and distance are all laid out. Finding the right fit is a matter of matching the cards to whatever Carthage week you're actually having.

Confidentiality & consent in South Dakota
Minor consent and partner treatment (EPT) under state law, plus how to test privately
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).
Can a minor consent on their own?
In South Dakota, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
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.
