Available testing centers
9 testing options are listed for Portsmouth, NH. The nearest, Greater Seacoast Community Health, is about 0.4 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.

Greater Seacoast Community Health in Portsmouth sees patients by appointment and covers gonorrhea, chlamydia, syphilis, herpes, HIV, and hepatitis A, B, and C testing in a single visit, with same-visit bacterial treatment, sliding-scale fees, and interpretation services available.
Without language access at the clinic itself, a diagnosis that needs follow-up (a reactive hepatitis result, a treatment plan, a PrEP conversation) can stall in confusion and go unaddressed. At Greater Seacoast Community Health, interpretation services are available on-site, so nothing in the care process gets lost between languages.
Greater Seacoast Community Health prescribes both PrEP and PEP directly, which means HIV prevention medication and an ongoing prescribing relationship stay with the same provider who manages testing and treatment.
Hepatitis C antibody testing without treatment capacity leaves patients to find specialty care on their own, a gap that delays or ends curative treatment for many. Greater Seacoast Community Health treats hepatitis C on-site, closing that gap entirely.

No separate infectious-disease referral required to start or continue either.
The panel at Joan G Lovering Health Center covers gonorrhea, chlamydia, syphilis, and herpes alongside both rapid and conventional HIV testing. Six distinct tests rather than four. Adding herpes to the panel changes what a single appointment can actually rule out or confirm.

STD stats & rates
How reported STI rates in Rockingham County, the county that includes Portsmouth, compare with New Hampshire and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~26% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#5 of 10 New Hampshire counties for chlamydia, a higher rate than 50% of the state
| Infection | Rockingham County | New Hampshire | United States |
|---|---|---|---|
| Chlamydia | 154 494 cases ▼ 22% | 196.6 | 492.2 |
| Gonorrhea | 31.8 102 cases ▼ 24% | 41.9 | 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 Rockingham County, chlamydia has fallen from 171.2 to 154 per 100,000 (10%), gonorrhea has risen from 26.7 to 31.8 per 100,000 (19%), and P&S syphilis has risen from 3.2 to 4.4 per 100,000 (38%).

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 Rockingham County.
Local HIV snapshot
Rockingham County HIV care continuum (2023)
Rockingham County recorded 2.9 new HIV diagnoses per 100,000 (2023), against 2.8 statewide and 13.7 nationally. Among Rockingham County residents living with HIV, 81.2% are in care · 74.6% 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 Rockingham County tests for syphilis.

Data & references
Local context
The stretch of Lafayette Road between Water Country and the older ranch neighborhoods of Portsmouth Plains tells you a lot about how this city actually moves, mostly by car, across distances that make a quick errand feel like a planned trip. For younger adults in their late teens and twenties, that calculus shapes whether a routine STI screening ever gets scheduled at all. With nearly half of Portsmouth residents renting, many of them paying over thirteen hundred dollars a month, discretionary time and money carry real weight, and a test that requires taking a half-day off a job in a city where most working-age adults are employed full-time is a test that gets delayed. The economic profile here is genuinely mixed.
A large share of households clear six figures, yet the rental burden in a high-cost market like this means that even comfortably employed renters are running lean on margin. That tension is sharpest for people in their mid-twenties navigating relationships, shared apartments, and jobs without flexible hours. Exactly the years when screening is most consequential. The listed options on this page represent a real range of schedules and fee structures, which matters when I-95 and Spaulding Turnpike are your only reliable arteries and the West End isn't exactly a walk from anywhere a clinic tends to anchor itself.
Getting there
At 9.53/20 on the EPA walkability index, day-to-day errands in Portsmouth 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 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).
In New Hampshire, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
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.
