No Bill for Any Service Here
Convenient MD Urgent Care in Merrimack charges nothing for any of its services: testing, treatment, and the mpox vaccine included. For anyone paying out of pocket or without a regular provider to bill through, that standing policy means care without a cost calculation attached to every decision.
Harbor Care Health and Wellness Center in Nashua welcomes walk-ins for STI screening, no appointment needed. Federally qualified status anchors its sliding-scale fees, adjusting costs to income so anyone can afford a visit covering syphilis, gonorrhea, and chlamydia testing in one stop.
Dartmouth Health in Nashua charges nothing for any service it provides: HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B and C, and TB testing are all free, as are same-visit bacterial treatments, HPV and hepatitis A vaccines, and PrEP. Appointments are required.

Every Service Here Is Free of Charge
The zero-cost structure at Dartmouth Health isn't a discount tier or income-screened program: it's operationally baked into Ryan White and public-health funding that covers staffing, labs, and medications alike. PrEP prescriptions, hepatitis C treatment, and HIV medical management are all included under that same funding umbrella, with no separate billing pathway.
Spanish Spoken On-Site, Interpretation Beyond That
Spanish is available as a direct-service language at Dartmouth Health in Nashua, meaning clinical conversations (risk counseling, medication adherence education, TB treatment protocols) happen in Spanish without routing through an intermediary. For other languages, interpretation services are operationally in place across the full range of appointments.
Ryan White Carries HIV Care Past the Test
Many testing sites hand off a positive result to a separate HIV care provider, leaving a gap between diagnosis and ongoing management. Dartmouth Health's Ryan White funding closes that gap: rapid and conventional HIV testing, medical treatment, and medication adherence counseling all run continuously within the same clinic.

Zero-Dollar Care Backed by Real Billing Structure
Harbor Care's sliding scale is staffed and structured to absorb the full cost: the clinic carries a no-fee tier built into its fee schedule, so the panel, treatment, vaccines, and PrEP prescriptions are all invoiced at zero when income qualifies. No separate application, no secondary program enrollment.
Spanish and Interpreted Care on Staff
Harbor Care provides services directly in Spanish, with interpretation available for additional languages beyond that: meaning clinical conversations about medication adherence, hepatitis C treatment protocols, and PrEP dosing happen in the language a patient uses naturally, not through a secondary layer.
PrEP Prescribed and Managed Here for the Long Term
For anyone without a regular prescriber, paying cash or navigating gaps in coverage, Harbor Care holds the full PrEP capability in one place: initial evaluation, prescription, and the ongoing medication adherence counseling that keeps the regimen effective over time.

No Fee Means No Deferred Care
When cost is part of the equation, a fee at any point in care (testing, treatment, counseling) can be the reason something goes untreated. At the Nashua Division of Public Health and Community Services, every service, from the initial test through STI treatment and PrEP, carries no charge, so cost never becomes the reason a visit doesn't happen or a prescription goes unfilled.
ASL, Chinese, French, and Haitian Creole on Staff
The Nashua Division of Public Health and Community Services delivers care directly in American Sign Language, Chinese, French, and Haitian Creole: meaning the clinical conversation, not just check-in, happens in a language the patient uses fluently, which matters when the topic is a treatment plan, a prevention medication, or a TB protocol.
PrEP and PEP Both Available On-Site
The Nashua Division of Public Health and Community Services prescribes both PrEP and PEP, which means a patient leaving with a prevention plan leaves with an actual prescription, not a referral to sort out elsewhere, keeping the gap between decision and medication as short as possible.

Lamprey Health Care in Nashua runs by appointment and covers gonorrhea, chlamydia, syphilis, rapid and conventional HIV, and TB testing on a sliding-scale fee accepted by Medicaid, Medicare, and most insurers: bacterial STIs treated same visit, HPV and hepatitis A and B vaccines available, with care delivered in Portuguese and Spanish.

Substance-Use Treatment Staffed Alongside STI Care
Lamprey Health Care maintains substance-use treatment as a named clinical service, not a separate referral track. A patient managing both an STI and a substance-use condition is seen within the same practice, where providers can coordinate prescribing, monitor treatment progress, and schedule follow-up together rather than across disconnected programs.
Title X Covers Minors With Legally Confidential Appointments
As a Title X-funded site, Lamprey Health Care is legally required to keep family planning services for minors confidential: meaning the visit, testing, and any resulting care are not disclosed to a parent or guardian without the patient's consent. That protection is built into Title X's federal framework and governs how records are handled operationally.
Portuguese and Spanish Are Working Clinical Languages Here
Portuguese and Spanish are staffed languages at Lamprey Health Care in Nashua: used in the exam room, during counseling, and across the care visit itself. That means prescriptions are explained, symptoms are discussed, and follow-up instructions are given directly in the language the provider and patient share.
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 2 miles away; if you'd rather skip the trip, an at-home kit ships to Merrimack, 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.

Hillsborough recorded 4.6 new HIV diagnoses per 100,000 (2023), against 2.8 statewide and 13.7 nationally. Among Hillsborough residents living with HIV, 78.6% are in care · 72.6% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.

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 Hillsborough tests for syphilis.

Merrimack's rhythm turns on work and family: the kind of place where people buy a house and stay, where weekday mornings move fast and weekends belong to the people you live with. That stability, though, can make health questions feel harder to ask, especially the ones you'd rather keep private. Confidential STI testing in and around Merrimack lets you get screened without announcement or delay, on your own timeline, whether you're establishing a new relationship or simply keeping routine care current. The testing sites listed on this page sit within reach of most residents.
Walk-in appointments and online scheduling both exist; same-day results are common at several locations. Because many people here work full schedules or manage household responsibilities, clinics near Everett Turnpike and Daniel Webster Highway stay open into evening hours and offer weekend slots. Practical scheduling for lives that don't pause. Young adults especially benefit from straightforward, judgment-free screening.
Merrimack's strong sense of community can make privacy feel precious, which is why knowing that test results stay confidential (not shared with employers, family, or neighbors) matters so much here. Testing is a private choice, and the process is built to keep it that way.

Confidentiality & consent in New Hampshire
Minor consent and partner treatment (EPT) under state law, plus how to test privately
Two things that actually depend on New Hampshire 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 New Hampshire, 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)
New Hampshire 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.
