Greater Baden Medical Services tests for gonorrhea, syphilis, chlamydia, and HIV on a sliding-scale fee open to all patients, with appointments required and same-visit treatment available for bacterial infections. Closing on Spanish-language and interpretation-supported care.
When a clinic can't conduct a real conversation (about symptoms, history, or a diagnosis) patients leave without fully understanding their care, and conditions go untreated. At Greater Baden Medical Services in La Plata, Spanish-language care and interpretation services for other languages are woven into the visit itself, so nothing critical gets lost between the exam and the door.
Many STI clinics cap their panel at four infections and leave herpes and hepatitis testing to a separate provider. Greater Baden Medical Services in La Plata runs tests for herpes, hepatitis A, hepatitis B, and hepatitis C alongside gonorrhea, syphilis, chlamydia, and HIV. One appointment covering what would otherwise take two.

Maryland Department of Health in White Plains tests for HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B and C, and TB, with same-visit treatment for bacterial STIs, on a sliding-scale fee structure, with all services ultimately provided at no cost.
Whether someone is paying entirely out of pocket, managing a chronic condition like hepatitis B, or starting PrEP without insurance coverage, Maryland Department of Health in White Plains absorbs the full cost of every service it provides. No bill follows the appointment, for testing, treatment, or prevention.
Without Spanish-language care on-site, a patient leaves with instructions they may misread, a follow-up they may not book, and a treatment window that quietly closes. Maryland Department of Health in White Plains delivers care directly in Spanish, and offers interpretation for other languages, so nothing critical is lost between the appointment and the outcome.
Maryland Department of Health in White Plains prescribes doxycycline post-exposure prophylaxis (DoxyPEP), a bacterial STI prevention regimen taken after a potential exposure, alongside both PrEP for HIV prevention and PEP. Holding all three means prevention is calibrated to the specific risk, not the nearest available option.

University of Maryland Medical System in Waldorf tests for HIV, syphilis, gonorrhea, chlamydia, hepatitis A, B, and C, and TB on a sliding-scale fee with insurance accepted; appointments are required, and bacterial infections can be treated the same visit.
Leaving a clinic with a prevention need and no prescription means days lost tracking down a prescriber willing to take it on. University of Maryland Medical System in Waldorf carries both PrEP and PEP in-house, so the gap between identifying risk and holding a prescription doesn't open in the first place.
University of Maryland Medical System in Waldorf provides hepatitis C treatment on-site, not a workup followed by an outside referral. That continuity keeps the treatment relationship with the same clinical team that handled the diagnosis, shortening the timeline from confirmed infection to active management.
The panel at University of Maryland Medical System in Waldorf includes hepatitis A, B, and C alongside HIV, syphilis, gonorrhea, chlamydia, and TB. Meaning a single appointment surfaces infections that a narrower panel would leave undetected and untreated.

STD stats & rates
How reported STI rates in Charles County, the county that includes Port Tobacco, compare with Maryland and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~21% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#6 of 24 Maryland counties for chlamydia, a higher rate than 75% of the state
| Infection | Charles County | Maryland | United States |
|---|---|---|---|
| Chlamydia | 557.6 959 cases ▼ 4% | 579.8 | 492.2 |
| Gonorrhea | 190.1 327 cases ▼ 8% | 207.1 | 179.5 |

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 Charles County, chlamydia has fallen from 590 to 557.6 per 100,000 (5%), gonorrhea has risen from 181.9 to 190.1 per 100,000 (5%), and P&S syphilis has fallen from 12.6 to 11 per 100,000 (13%).

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 Charles County.
Local HIV snapshot
Charles County HIV care continuum (2023)
Charles County recorded 9.7 new HIV diagnoses per 100,000 (2023), against 13.9 statewide and 13.7 nationally. Among Charles County residents living with HIV, 79% are in care · 72.8% 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 Charles County tests for syphilis.

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.
