This page is general health information, not medical advice. It cannot tell you whether you have an infection. A clinician can, and the testing options on this site are a good place to start.

Not having insurance does not close the door on testing in Chicago. The city has a public health department with sexual health clinics, a county health system with a walk-in screening clinic, and nonprofit clinics that use sliding fee scales.

This guide helps you compare those options. It covers what to look for in a testing site, what each setting says about cost, which questions to ask about bundled panels, and which warning signs to watch for.

One honest note up front. Most Chicago clinics do not publish a price list online. Where a price is not published, this guide says so and tells you what to ask.

How much is an STD test in Chicago without insurance?

The honest answer is that it depends on the setting, the tests you choose and your income. Here is what the sources we checked actually say.

Setting	What is published about cost
Chicago Department of Public Health (CDPH) sexual health clinics	CDPH says care is provided regardless of ability to pay or insurance status. It asks insured patients to bring an insurance card. The page does not say the visit is free and does not list a price.
Cook County Health, Ruth M. Rothstein CORE Center	The CDC GetTested listing for this site shows insurance accepted, Medicaid accepted, Medicare accepted, PrEP for uninsured people and a sliding scale. No dollar amounts are listed.
Howard Brown Health	Howard Brown calls its walk-in clinic "quick and low-cost service" and offers a Sliding Fee Discount Program based on income and family size. Its page does not list a test price.
Planned Parenthood of Illinois, Rogers Park	The CDC GetTested listing shows insurance and Medicaid accepted. It does not say whether self-pay or a sliding scale is offered, so ask when you call.
Urgent care and lab-order services	We did not find a published Chicago price range for these. Ask for an itemized, self-pay price in writing before any sample is taken.

So the STD test cost you will actually pay is something to confirm by phone. A sliding scale generally means the fee is set by your income and household size, so bring whatever proof of income the clinic asks for.

What to look for in a testing site

When you compare options for cheap STD testing in Chicago, price is only one signal. These are the quality indicators that matter more.

A real clinical setting

A good site is run by clinicians who can review your results with you, answer questions and prescribe treatment if it is needed. The CDC STI Treatment Guidelines (2021) describe testing and treatment as part of one clinical pathway. A site that tests but cannot connect you to care leaves a gap.

Tests matched to your situation

Different infections are tested in different ways. Depending on your history, a clinician may use a urine sample, a swab or a blood draw. The CDC says the right tests depend on your age, anatomy, sexual practices and recent exposures. A site that asks about these things is doing its job.

Clear information about timing

Every test has a window period, which is the time after an exposure when a test may not yet detect an infection. The CDC publishes window periods for each infection. A good clinic will explain the timing that applies to you and tell you whether a repeat test makes sense.

A plan for results

Ask how and when you will hear back, and who to call with questions. Ask what happens if a result needs follow-up care.

Respect and privacy

You should be treated without judgment, whatever your gender, orientation or number of partners. Many Chicago clinics, including Howard Brown Health, serve LGBTQ+ communities and say so.

Key features to compare

Use this checklist when you call or read a clinic page.

Walk-in or appointment. This changes how fast you can be seen.
Cost model. Sliding scale, ability-to-pay policy or a flat self-pay fee.
Which tests are included. HIV, syphilis, chlamydia, gonorrhea, hepatitis B and C and others.
Same-day treatment. Some sites can prescribe on the spot, and some send you elsewhere.
Prevention services. PrEP, PEP and doxy-PEP, which clinicians prescribe after an assessment.
Hours and location. Check the days, the lunch closure and the transit route.

Options by setting

These are not rankings or endorsements. They are the public and nonprofit options with published details, grouped by how they work. For the full local list, see our list of Chicago testing sites.

Health department clinics

CDPH runs Sexual Health Specialty Clinics that offer STD testing, HIV testing, PrEP and treatment. Per the CDPH page, you should call for an appointment, and limited walk-ins are available. The clinics close from 12 to 1 pm daily and on City holidays, and CDPH says to call the clinic to verify hours.

County walk-in screening

The Ruth M. Rothstein CORE Center, run by Cook County Health, is at 2020 W. Harrison St., Chicago, IL 60612. Cook County Health says the walk-in STI Screening Clinic can be reached by phone Monday through Friday, 8:30 am to 3:30 pm, at 312-572-4700, and that same-day HIV and STI services are provided. For appointments, the Access Line is 312-572-4500. See the Cook County Health HIV program page.

Nonprofit walk-in clinics

Howard Brown Health offers a sexual health walk-in clinic with no appointment necessary. Patients are seen first come, first served. Its page lists HIV, rapid HIV, syphilis, chlamydia, gonorrhea, hepatitis A, B and C testing, treatment, PEP and PrEP. Doxy-PEP is offered by appointment. Call 773.388.1600 for any location.

Sheridan: 4025 N. Sheridan Rd., Chicago, IL 60613
63rd St.: 641 W. 63rd St., Chicago, IL 60621
Broadway Youth Center: 1023 W. Irving Park Road, Chicago, IL 60613. Howard Brown describes its youth services as for ages 12 to 24.

See the Howard Brown walk-in clinic page and its financial assistance page.

Planned Parenthood of Illinois

The Rogers Park Health Center, 5725 N Broadway, Chicago, IL 60660, lists STD testing, HIV testing and HPV vaccine. The CDC GetTested listing says an appointment is required. The phone is (773) 942-7193. GetTested notes that hours may change, so confirm before you go.

A free option for HIV only

Erie Family Health Centers, a Chicago nonprofit health center, offers a free rapid HIV test kit by online request or by phone at 312-386-6344. It is for Illinois residents age 17 or older. It tests for HIV only, not other STIs. Details are on the Erie Family Health Centers test kit page. We did not find a state or city mail-order program for free home STI tests.

Using Medicaid and Illinois programs

If you have Medicaid, check the listing before you go. CDC GetTested shows Medicaid accepted at the CORE Center and at Planned Parenthood of Illinois, Rogers Park. If you are unsure whether you qualify for coverage, ask any clinic whether a financial counselor can help.

For prevention, the Illinois Department of Public Health (IDPH) runs PrEP4Illinois, a PrEP medication assistance program. It requires Illinois residency documentation dated within 90 days and proof of any insurance. The helpline is 1-833-773-7445. IDPH also issued a statewide standing order in April 2025, so Illinoisans can get PrEP from a trained pharmacist without first needing a doctor's prescription.

The Illinois HIV/STD Hotline, 1-800-243-2437, is listed on the IDPH STD page.

What to ask about bundled panels

Many places sell a "full panel" or a package. These can be a good value or a way to pay for tests you did not need. Ask these questions.

Which infections are in the panel, listed one by one?
Does the panel include HIV, syphilis, chlamydia and gonorrhea? Are hepatitis B and C included?
Does it test every body site that applies to me, such as throat or rectal swabs when relevant?
Is the visit fee separate from the lab fee?
If a result is positive, is treatment included, or billed separately?
Can I choose individual tests instead of the bundle?

The CDC STI Treatment Guidelines (2021) say screening should be tailored to the person. A bundle that fits your situation is useful. A bundle that does not is just a higher bill.

What public numbers say about Chicago

Testing is common here because these infections are common. The IDPH STI Section's county table for 2022 reports a chlamydia rate of 1,023.7 per 100,000 people (27,596 cases) in the City of Chicago, and a gonorrhea rate of 459.3 per 100,000 (12,382 cases). For comparison, CDC's 2023 state tables list Illinois at 557.7 per 100,000 for chlamydia and 202.3 per 100,000 for gonorrhea. These come from different years, so compare them loosely.

The point is not to alarm anyone. Most bacterial STIs are curable with treatment from a clinician, and the CDC says testing is how people find out so they can get care.

Red flags to avoid

No itemized price. If a site cannot tell you what you will owe before testing, ask for it in writing or go elsewhere.
Promises that sound absolute. No test is perfect. Be wary of anyone who calls a test "guaranteed" or "100%" accurate.
A result with no clinician. If no one can explain a result or connect you to care, that is a gap.
Pressure to buy extras. You can decline add-ons and ask for what a clinician recommends.
Vague or missing contact details. A real clinic lists an address, a phone number and hours.
Shaming language. Good care is respectful. If you feel judged, you can leave.

Privacy, minors and partners

Under the Illinois Consent by Minors to Health Care Services Act (410 ILCS 210/4), a minor age 12 or older who may have come into contact with a sexually transmitted disease can consent to care related to prevention, diagnosis or treatment. Parental consent is not necessary. The law also says providers make reasonable efforts to involve the family if they believe it will not be harmful, and that each STD incident must be reported to public health.

On reporting: under Illinois Administrative Code Part 693, HIV, syphilis, gonorrhea, chlamydia and chancroid are reportable. In Chicago, clinicians send case reports to the local health department within seven days of diagnosis or treatment. Ask the clinic how billing statements are handled if you are on someone else's insurance plan.

For partners, the CDC says Illinois law permits expedited partner therapy for chlamydia, gonorrhea and trichomoniasis. That means a clinician may provide treatment for partners exposed in the previous 60 days. Syphilis is not covered. Ask your clinician whether it applies to you.

Where to go next

Start by choosing one setting from the list above and calling. If you want to browse more sites, the CDC's GetTested locator lets you look up testing sites by ZIP code. For a deeper comparison of Chicago clinics and what each charges, read our guide to where to get tested in Chicago and what it costs.

A short call script can help: "I do not have insurance. What is the self-pay or sliding-scale price for testing, and which tests are included?" That one sentence gets you most of what you need.
