A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Greater Baden Medical Services in Lexington Park runs on a sliding-scale fee open to everyone, accepts Medicaid and private insurance, and requires an appointment for testing that covers gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis A, B, and C, and TB. With same-visit treatment for bacterial infections.
Clinics that serve non-English speakers often patch the gap with a phone line rather than a person in the room. Greater Baden Medical Services keeps Spanish-speaking staff on site and arranges interpretation across other languages, so the clinical conversation (symptoms, history, treatment instructions) happens without an intermediary device between patient and provider.
For anyone without a regular primary-care provider (paying on a sliding scale, navigating care without continuity) Greater Baden Medical Services carries herpes and hepatitis A, B, and C testing alongside the standard gonorrhea, chlamydia, syphilis, and HIV panel, so a single appointment covers exposures that a bare-minimum panel would leave unexamined.

NP Family Practice in Leonardtown handles gonorrhea, chlamydia, syphilis, herpes, and the full hepatitis panel with same-visit treatment for bacterial infections confirmed on-site. Fees run on a sliding scale and insurance or Medicaid is accepted; appointments are required.
PrEP at NP Family Practice means an ongoing clinical relationship: the prescribing provider orders the required baseline labs, writes the prescription, and schedules the follow-up monitoring that the regimen demands. PEP is also available, managed through the same practice rather than handed off elsewhere.
Plenty of STI-focused sites test for gonorrhea, chlamydia, syphilis, and HIV and stop there: herpes serology and hepatitis A, B, and C screening fall outside what they offer. NP Family Practice runs all of those, so a single appointment covers infections that would otherwise require a separate referral.

STD stats & rates
How reported STI rates in St. Mary's County, the county that includes Lexington Park, compare with Maryland and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~40% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#20 of 24 Maryland counties for chlamydia, a higher rate than 17% of the state
| Infection | St. Mary's County | Maryland | United States |
|---|---|---|---|
| Chlamydia | 253.3 292 cases ▼ 56% | 579.8 | 492.2 |
| Gonorrhea | 80.7 93 cases ▼ 61% | 207.1 | 179.5 |
| Syphilis (P&S) | 0.9 1 cases ▼ 94% | 14.2 | 15.8 |
| Syphilis (early) | 2.6 3 cases ▼ 82% | 14.6 | 16 |

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 St. Mary's County, chlamydia has fallen from 362.1 to 253.3 per 100,000 (30%), gonorrhea has fallen from 233.8 to 80.7 per 100,000 (65%), and P&S syphilis has fallen from 5.3 to 0.9 per 100,000 (83%).

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 St. Mary's County.
Local HIV snapshot
St. Mary's County HIV care continuum (2021)
St. Mary's County recorded 6.3 new HIV diagnoses per 100,000 (2021), against 13.9 statewide and 13.7 nationally. Among St. Mary's County residents living with HIV, 82.2% are in care · 75.7% 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 St. Mary's County tests for syphilis.

Data & references
Local context
Southampton sits close enough to the MD 235 corridor that errands run together (gas, groceries, a pharmacy stop) but a clinic visit is a different calculation when you're renting rather than owning, and in Lexington Park the majority of households are renters absorbing rents that leave little room for unplanned medical costs. That financial reality shapes whether people follow through on routine screening or quietly file it away for later. The community here skews notably young, with a large share of residents in the late-teens-through-early-thirties stretch of life. Exactly the years when new relationships and shifting living situations make regular STI testing most useful and most likely to be skipped.
Households in Lexington Park run large on average, meaning schedules get complex fast, and with most adults actively employed and unemployment unusually low, the hours that clinics are open genuinely compete with the hours people are working. Getting to a testing site in a county where walking rarely solves the transit question means carving out time and fuel for a deliberate trip down Great Mills Road or Three Notch Road, not just stepping out at lunch. The options listed on this page span a range of fees and hours, which matters when you're coordinating around a job, shared transportation, and a household that doesn't have much scheduling slack. Colony Square and Jonestown residents have different distances to cover, but the starting point for everyone is the same: knowing the options exist.
Getting there
At 6.49/20 on the EPA walkability index, day-to-day errands in Lexington Park 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 Maryland 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 Maryland, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Maryland 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.
