All of One Medical's Chicago locations offer same-day on-site lab testing on a walk-in basis with the personal touch our friendly phlebotomists and technicians. While drawing blood or performing tests, we try to keep patients as comfortable as possible, assuring that they’re relaxed before getting started. Lab testing is available daily, from 8am until 4pm with convenient extended hours at our Loop - W Madison office on Tuesday, until 7pm. Appointments aren’t necessary, just an order from your provider. One Medical will get your results back quickly and securely.

How can I get lab services at One Medical?

If you're interested in having a specific lab test, feel free to talk to your primary care provider about it during your visit or email your provider in advance. Usually, your provider will decide whether you need lab tests based on what they learn during your visit, your current health and any medications you might be taking. Most younger people - specifically those in their 20s and 30s - who are generally healthy won't need tests very often. But if there's a specific health condition you're managing, your provider may request lab work more frequently.

When are the on-site labs open?

Please refer to the local office pages for specific lab hours.

Will insurance cover my lab tests?

Every insurance plan is different, and the details of your coverage depend on your specific policy. While most lab tests are generally covered by insurance, you may want to contact your carrier before visiting the lab in order to ensure coverage.

If I’m new to One Medical, should I have labs done prior to my first visit?

No. In order to make sure we don’t waste your time or money, we’d like to meet you first. Your provider then can assess which tests are needed and write you the appropriate lab orders. You can transfer your existing medical records to us electronically - just use the medical record request form in My One.

Should I fast before my lab test?

Your provider will talk to you about how to prepare for your lab test. Some tests don’t require fasting, but others do in order to get accurate results. If you’re having a test that requires fasting, that means you cannot eat or drink anything besides water for the 12 hours before your test. (The only exception is medication you regularly take.) Filling up on water means that it will be easier to draw blood during your test.

How and when will I get my lab test results back?

Your lab tests will be processed by a third party and then returned to One Medical. A board-certified provider on our Virtual Medical Team will review your results and email you within seven to 10 business days of your test, along with an explanation of the results and suggestions on what you need to do next.

Can I get STD and HIV testing done at One Medical?

Yes. We keep STD test results completely confidential, as we do with all medical tests. If you believe you were exposed to HIV or viral Hepatitis, contact your provider immediately to discuss early preventive treatment options.
