Rated 4.2 out of 5 from 32 reviews

Methodist Hospitals in Merrillville brings the diagnostic infrastructure of a hospital to STI care: rapid and conventional HIV testing, the standard bacterial panel, same-visit treatment for gonorrhea, chlamydia, and syphilis, all on a sliding scale with walk-ins welcome. PrEP and PEP are available on-site.

Read full overview

PrEP and PEP Managed Where You Already Test

Methodist Hospitals prescribes both PrEP and PEP directly, without routing those conversations to a separate provider. That means a patient's testing results and prevention plan live in the same clinical relationship, making it easier to start, adjust, or sustain either medication over time.

Hepatitis B and C Tested Alongside the Standard Four

Walk-in STI clinics often test only for the four bacterial-and-viral basics, leaving hepatitis to a separate appointment elsewhere. Methodist Hospitals tests for both hepatitis B and hepatitis C in the same visit, along with TB, so a single stop covers infections that a narrower panel would miss entirely.

Rated 3.1 out of 5 from 73 reviews

Planned Parenthood Great Northwest Hawaii Alaska Indiana Kentucky in Merrillville runs a full appointment-based STI clinic (rapid HIV, herpes, hepatitis B and C, syphilis, gonorrhea, and chlamydia) on a sliding-scale fee open to all, with same-visit treatment for bacterial infections and interpretation services available.

Read full overview

Interpretation Services Extend to Every Clinical Exchange

Interpretation services are available for non-English languages throughout the visit, which means nuanced conversations (about DoxyPEP dosing, PrEP eligibility, or a positive herpes result) happen in the language a patient reasons in, without stripping clinical detail in the process.

Title X Covers Minors With Legal Confidentiality

As a Title X-funded clinic, Planned Parenthood Great Northwest Hawaii Alaska Indiana Kentucky in Merrillville provides legally confidential family planning and STI services to minors. Meaning consent and records are handled independently of a parent or guardian, a specific protection that Title X mandates rather than leaves to clinic discretion.

PrEP, PEP, and DoxyPEP Available From One Provider

For anyone without a regular prescriber for HIV or bacterial STI prevention, this clinic holds all three: PrEP for ongoing HIV risk reduction, PEP for post-exposure management, and DoxyPEP, the doxycycline regimen taken after potential bacterial STI exposure, so prevention doesn't require splitting care across multiple providers.

Ryan White Carries HIV Care Past Diagnosis

Testing-only HIV programs hand off a positive result with nowhere to go for ongoing medical management. Community HealthNet's Ryan White funding closes that gap: HIV diagnosis, medical treatment, and long-term care are all staffed and sustained at the same site in Merrillville.

PrEP Prescribed and Monitored On-Site

Plenty of clinics screen for HIV without the clinical infrastructure to prescribe or follow a prevention regimen. Community HealthNet maintains the prescribing, lab monitoring, and follow-up appointments that PrEP and PEP each require. Handled directly by the staff in Merrillville.

Zero-Balance Care Is Structurally Built In

The no-fee structure at Community HealthNet isn't a grant-funded carve-out for a single test, it runs across all services the clinic provides. Billing is absorbed through the funding mix of Ryan White, sliding-scale adjustments, and accepted public and private insurance, so the cost to a patient landing at zero is zero.

Rated 4.4 out of 5 from 1282 reviews

NorthShore Health Centers in Merrillville is a community health center, which means STI care sits alongside the fuller infrastructure of primary medicine: walk-in testing for gonorrhea, chlamydia, syphilis, rapid and conventional HIV, hepatitis C, and TB, on a sliding-scale fee open to everyone, with same-visit treatment for bacterial infections and PrEP and PEP on-site.

Read full overview

Prevention Prescriptions Require More Than a Test

Sexual health clinics that test but can't prescribe leave a gap between result and protection, someone who needs PrEP starts over at a primary care office. NorthShore closes that gap: both PrEP for ongoing prevention and PEP are prescribed and managed on-site in Merrillville.

Substance-Use Treatment Staffed Inside the Same Clinic

NorthShore's substance-use treatment isn't a referral to a separate program: it's a clinical service within the same Merrillville facility, meaning providers can coordinate medication, monitoring, and STI care through a shared chart rather than across disconnected offices.

Hepatitis C Testing Added to the Standard Panel

NorthShore tests for hepatitis C alongside gonorrhea, chlamydia, syphilis, and HIV, and backs hepatitis A and B exposure with on-site vaccination. That means a single visit in Merrillville can address both active infection screening and immunity gaps across the full hepatitis spectrum.

Prevention Prescriptions Go Beyond the Test

Plenty of testing sites hand off prevention prescribing entirely, Edgewater Health writes both PrEP and PEP in-house. That means the clinic managing your results is the same one authorizing the medication, with no separate provider to locate or schedule.

Hepatitis C Rounds Out the Standard Four

Edgewater Health's panel runs to six infections: rapid HIV, conventional HIV, syphilis, gonorrhea, chlamydia, and hepatitis C. Adding hepatitis C to the same visit means chronic viral exposure gets screened alongside acute bacterial risk without a separate appointment or lab order.

Powers Health in Hobart accepts Medicaid and most insurance, with fees for those paying directly; the clinic covers STI treatment, HIV/AIDS care, hepatitis B and C, TB, and bacterial STIs treated same visit, by appointment, with PrEP, PEP, and DoxyPEP available for prevention.

Read full overview

Three Prevention Tools, One Clinical Relationship

Powers Health prescribes PrEP, PEP, and DoxyPEP under one ongoing care relationship: meaning adherence counseling, refills, and any needed follow-up stay with the same clinical team rather than fragmenting across providers.

Hepatitis C Treatment Starts and Stays Here

Without on-site hepatitis C treatment, a confirmed diagnosis often becomes the beginning of a second search. New provider, new intake, delayed antivirals. Powers Health carries treatment through to completion, so a positive result doesn't leave patients navigating an entirely separate care system.

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.

Among Lake County residents living with HIV, 69.6% are in care · 58.4% 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.

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 Lake County tests for syphilis.

Local context

About Merrillville, IN

Mallard Bay Apartments and the Turkey Creek Meadows corridor house a lot of Merrillville's younger renters: people freshly splitting costs with a roommate or two, navigating that period when relationships are new and annual checkups still feel optional. With roughly a third of residents renting at just over a thousand dollars a month, healthcare appointments compete directly with rent, groceries, and the other non-negotiables. Add an unemployment rate that leaves a meaningful slice of the workforce between jobs and therefore between insurance plans, and the calculus around paying out-of-pocket for screening gets real fast. Getting around makes it more complicated.

Merrillville is built around US 30 and SR 53, wide commercial corridors that are genuinely hard to navigate without a car. The clinics listed on this page are spread across those routes, which means access depends on having a vehicle, a ride, or a flexible enough schedule to piece one together. For younger adults still sorting out their routines, that logistical bar is exactly where testing quietly gets skipped. Lake County's STI rates give good reason not to skip it.

With the majority of Merrillville households occupied by families averaging more than three people, a single undetected infection moves through a shared life quickly. Clinics along Broadway offer same-day or walk-in slots, which, for someone squeezing an errand between shifts near Collins Park, can be the detail that actually changes the outcome.

Confidentiality & consent in Indiana Minor consent and partner treatment (EPT) under state law, plus how to test privately

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).

Can a minor consent on their own?

In Indiana, 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)

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.
