Lab samples can be collected at both of our clinics, and a clinician orders only the tests that will guide your care.

Your provider explains every result, and results outside the normal range are not always a sign of a problem.
Tests we offer at a glance
Urgent Care Center of Westmont, also known as Immediate Care Center of Westmont, runs many tests during a walk-in visit and sends others to an outside lab.

Rapid tests for common infections
Rapid tests help us tell one infection from another, which matters because treatment is different. A swab of the nose or throat, a urine cup or a small blood sample is all most of them need.
Flu testing: a nose swab that checks for influenza A and B. Antiviral medicine is most helpful when started early.
COVID-19 testing: rapid antigen or PCR testing from a nose swab.
RSV testing: a nose swab, often used for babies, young children and older adults with cough or wheezing.
Strep throat testing: a throat swab. Strep is bacterial and is treated differently from a viral sore throat.
Mono screening: a blood test when tiredness, sore throat and swollen glands drag on.
UTI testing: a clean-catch urine sample, with a culture sent to the lab when needed.
Blood tests look at how your organs are working and help screen for common conditions before symptoms start. Our lab testing service collects the sample and sends it to the lab.
Full lab test panel: a complete blood count, metabolic panel and cholesterol in one draw.
Thyroid panel testing: TSH and related tests for tiredness, weight change or a racing heart.
Allergy testing: a blood test that measures your immune response to pollen, dust, pets and foods.
TB testing: a skin test read in 2 to 3 days, or a blood test that needs one visit.
Some blood tests require fasting. MedlinePlus says fasting usually means 8 to 12 hours with nothing but plain water. We'll tell you if fasting is needed for your test.
Private STD testing

Many sexually transmitted infections cause no symptoms, so testing is the only way to know. The CDC recommends that everyone ages 13 to 64 get tested for HIV at least once. Your visit starts with a private conversation, and your results are protected under federal law.
STD testing: a panel chosen to fit your history and symptoms.
X-ray is available only at our main clinic, 29 N Cass Ave, Ste A. Our clinic inside Jewel-Osco does not have X-ray. We use it to look for broken bones and dislocations and to check the lungs for pneumonia. MedlinePlus says the radiation from a chest X-ray is about the same as you get from the environment over about 10 days. Always tell us if you are or might be pregnant.
EKG
An EKG records your heart's electrical signals. Small sticky pads called electrodes are placed on your chest, arms and legs while you lie still. It is often part of a physical or job screening, or a check for a fluttering heartbeat. Chest pain is different: see the warning signs at the bottom of this page.
Non-DOT work drug screens
Read moreClose
Many employers ask for a drug screen before hiring. We offer non-DOT drug testing for job applicants and employers. MedlinePlus notes that urine is the most common sample, and a positive screen is usually confirmed with a follow-up lab test. We do not offer DOT drug tests for commercial drivers.
Bring a photo ID and any form or code from your employer.
Tell us about prescription and over-the-counter medicines you take.
Results go to your employer according to their program.
SwabA soft swab touches the inside of your nose or the back of your throat for a few seconds.
UrineYou collect a clean-catch sample in a cup in the restroom. We give you simple instructions.
Finger-stickA quick poke of the fingertip collects a few drops of blood for some tests.
Blood drawA small needle in the arm fills one or more tubes. Wear a shirt with sleeves that roll up.
Skin testFor a TB skin test, a tiny amount of fluid goes just under the skin. You come back in 2 to 3 days to have it read.
How results are shared
Read moreClose
A clinician reviews every result and explains what it means for you. For tests sent to an outside lab, we tell you at your visit how we will reach you when the results come in.
MedlinePlus explains that results are compared with a reference range, and it's common for healthy people to sometimes have results outside it. Your provider looks at your symptoms and history before deciding whether a result needs action or a repeat test. If you have questions, call (630) 324-6825.
How to prepare and what it costs

Bring a photo ID, your insurance card and any order or form from your doctor, school or employer.
Bring a list of every medicine and supplement you take, since some affect results.
We'll tell you if fasting is needed before a blood test.
Coverage for tests depends on your plan, so call to confirm. Self-pay visits start at $125, and tests may add to the cost. We tell you before anything is ordered. See cost and insurance for details.
Common questions
Do I need an appointment for lab work?
No. Walk-ins are welcome for lab work at both of our Westmont, IL clinics, 7 days a week. If you have an order from another doctor, bring it with you. You can also book a visit online to reserve a time at our Cass Ave clinic. We'll tell you if you need to fast first.
Do I need to fast before blood work?
Only for some tests. Cholesterol and blood sugar tests sometimes require fasting, which usually means nothing but plain water for 8 to 12 hours, per MedlinePlus. Many other blood tests need no preparation. We'll tell you if fasting is needed for your test, and keep taking your usual medicines unless we say otherwise.
Can I get an X-ray at the Jewel-Osco location?
No. On-site X-ray is available only at our main clinic, Urgent Care Center of Westmont, 29 N Cass Ave, Ste A, Westmont, IL 60559. Our clinic inside Jewel-Osco at 4 E Ogden Ave does not have X-ray. If you think you may need imaging, go straight to the Cass Ave clinic.
Is STD testing private?
Yes. Your visit, test choices and results are kept private and protected under federal law. You talk with the clinician one-on-one, and we discuss results only with you unless you give permission. Testing may use a urine sample, a swab or a blood draw, depending on the infection.
How will I get my test results?
A clinician explains your results and what they mean. For tests that are sent to an outside lab, we tell you at your visit how we will contact you once results arrive. If you have not heard from us when expected, call (630) 324-6825 and we'll check on it for you.
