Gennesaret Free Clinics in Indianapolis takes walk-ins for HIV, syphilis, gonorrhea, chlamydia, and hepatitis C testing: no appointment, no fee, and no donations required. Bacterial infections are treated same visit; HPV, hepatitis A, and hepatitis B vaccines are available on-site.
Gennesaret's no-fee structure applies across every service on the menu: testing, treatment, vaccines, and prevention education alike. Donations are accepted but never expected, meaning the full scope of care carries the same price regardless of what a visit involves.
Hepatitis C care at Gennesaret runs through a complete treatment cycle: direct-acting antivirals are prescribed and monitored in-clinic, so the work of clearing the virus, not just detecting it, happens under one clinical relationship. Sustained virologic response follow-up stays within the same practice.
Gennesaret's panel covers HIV, syphilis, gonorrhea, chlamydia, and hepatitis C in a single visit. Because hepatitis C is included from the start, a positive result moves directly into treatment planning without requiring a separate appointment at a different clinic.

Hendricks County Health Department in Danville is a public health department with STI testing built into its core mission: rapid HIV, syphilis, gonorrhea, chlamydia, and hepatitis C by appointment, with same-visit treatment for bacterial infections, on a sliding scale with no-fee options for all.
When cost sits between a person and treatment, infections go unmanaged and partners go untested. At Hendricks County Health Department, every service (testing, treatment, vaccines) is provided at no fee, so the decision to come in never hinges on what's in a wallet.
Many clinics leave non-English speakers to navigate the most sensitive parts of a visit without real support. Hendricks County Health Department provides interpretation services for non-English languages, so every exchange (history, results, treatment instructions) moves in a language the patient understands.
Missing a hepatitis C diagnosis means a separate appointment, a separate lab, and weeks of uncertainty that delay care. Hendricks County Health Department tests for hepatitis C alongside the standard bacterial panel and rapid HIV, so a single visit can surface infections that would otherwise go undetected until complications arise.

STD stats & rates
How reported STI rates in Hendricks County, the county that includes Plainfield, compare with Indiana and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~28% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#30 of 92 Indiana counties for chlamydia, a higher rate than 67% of the state
| Infection | Hendricks County | Indiana | United States |

| Chlamydia | 313.9 585 cases ▼ 36% | 491 | 492.2 |
| Gonorrhea | 71.4 133 cases ▼ 50% | 144 | 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 Hendricks County, chlamydia has risen from 241.4 to 313.9 per 100,000 (30%), gonorrhea has fallen from 77.8 to 71.4 per 100,000 (8%), and P&S syphilis has risen from 2.3 to 5.9 per 100,000 (157%).

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 Hendricks County.
Local HIV snapshot
Hendricks County HIV care continuum (2023)
Hendricks County recorded 12.9 new HIV diagnoses per 100,000 (2023), against 11.7 statewide and 13.7 nationally. Among Hendricks County residents living with HIV, 84.9% 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 Hendricks County tests for syphilis.

Data & references
Local context
US 40 cuts straight through Plainfield, and for anyone fitting a clinic visit into a workday, the drive east or west along East Main Street is usually the most practical route to the options listed on this page. That convenience matters more than it might seem, because Plainfield leans heavily toward ownership rather than renting, with typical home values well above the four-digit monthly rent that a sizable share of households carry. When housing costs take a real bite, a screening appointment with a sliding-scale or low-cost fee structure quietly moves from "optional" to something worth planning around. The community's profile adds texture to that picture.
Nearly two-thirds of working-age residents are in the labor force, and with fewer than three in ten households clearing six figures, cost and scheduling are genuine factors for most families. Households here average more than three people, and close to half of adults are married, which means a single positive result rarely stays a solitary concern. People in their late teens and twenties, who make up a meaningful share of Plainfield's population, tend to be in the highest-incidence years precisely because relationships are forming and testing habits aren't yet routine. That combination of larger households, dual responsibilities, and moderate incomes is exactly why Plainfield's testing landscape is worth knowing before the need is urgent rather than after.
Getting there

Two things that actually depend on Indiana 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 Indiana, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Indiana 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.
