Being seen close to home, without the awkwardness
When a clinic is this close, you may worry about running into a neighbor. Urgent Care Center of Westmont, also known as Immediate Care Center of Westmont, sees people every day for colds, sprains, physicals and lab work, so a visit here could be for anything. At the front desk, saying you would like testing is enough.
Your reason for the visit is discussed in a private exam room, not in the lobby.
Samples are collected by our clinical team at the clinic. Nothing is handed to you as a kit to take home.
Results are shared with you directly by a clinician.
Your records are private medical information under federal law. Our notice of privacy practices explains the details.
Matching tests to what you may have been exposed to

Common STD tests and what the CDC notes about each
Infection
Usual sample
What the CDC notes
Chlamydia
Urine or a vaginal swab
Often has no symptoms; retest about three months after treatment
Gonorrhea
Urine, plus a throat or rectal swab after oral or anal sex
Can infect the genitals, rectum and throat
Syphilis
Blood
The first sore often does not hurt and can go unnoticed
HIV
Blood
Everyone 13 to 64 should be tested at least once
Genital herpes
Swab of a sore
Without sores, a blood test may look for antibodies
Mention oral and anal sex, not only vaginal sex. The CDC notes that gonorrhea can infect the throat and rectum, and a urine test alone would not check those sites.
Your clinician helps choose from these based on your history. Some of our staff speak Spanish, so ask at the front desk if that would help. See which STDs are commonly tested and our STD testing service.
Clarendon Hills, IL and the DuPage County health department

Clarendon Hills, IL is a DuPage County village in Downers Grove Township. The DuPage County Health Department offers a public option: a confidential STD clinic at its Wheaton office that tests for chlamydia, gonorrhea, syphilis and HIV, for people 12 and older. Services for ages 12 to 17 are free there, and the department accepts Illinois Medicaid, Medicare and commercial insurance.
Our clinic one mile away is a walk-in option with weekend hours. Either choice is a sound one. What matters most is getting tested.
Insurance or self-pay for Clarendon Hills, IL residents

Clarendon Hills, IL had 8,702 residents in the 2020 Census, and close to 3 in 10 are under 18 (Census Bureau estimate). If you are covered on a parent's or spouse's plan, the visit and lab tests are billed to that plan, and the policyholder may receive a statement. If that worries you, self-pay is an option: a general visit starts at $125, and you can ask what each test costs before it is done.
Accepted plans include Blue Cross Blue Shield (PPO), BCBS Advocate Good Samaritan (HMO), BCBS Medicaid Community, Cigna, Humana, UnitedHealthcare, Medicare, Meridian, CountyCare, Multiplan/PHCS, ACPN, USAMCO and State of Illinois Benefit Plans. Call to confirm, and see cost and insurance.
Retesting, partners and lowering your risk
Read moreClose
If you test within days of a new exposure, your clinician may suggest coming back. Infections take time to show up on a test, and the CDC lists 23 to 90 days for HIV antibody tests. The CDC's prevention steps are simple:
Use condoms correctly every time you have sex.
Ask about vaccines for hepatitis B and HPV.
Get tested with a partner and share results.
If one of you has an STI, both should be treated at the same time.
Our main clinic at 29 N Cass Ave in Westmont, IL is about 1 mile west of the Clarendon Hills, IL village center in a straight line. You can drive west on 55th Street or ride Metra one stop west on the BNSF Line.
Will anyone in the waiting room know why I am there?
No one needs to. People come to our clinics for many reasons, from sore throats to physicals. You only need to say you would like testing at the front desk, and the details are discussed in a private exam room.
Can I walk in for an STD test after work?
Yes, on weekdays until 6 PM. Weekend hours are 9 AM to 5 PM. Walk-ins are welcome at both clinics, or you can use online check-in to hold a spot at 29 N Cass Ave.
Should I ask for a full STD panel?
Not always. There is no single standard panel. Your clinician recommends tests based on your symptoms, partners and the kinds of sex you have had. Read what a full STD check includes for more detail.
