Frequently Asked Questions

Do I need to go to Outpatient Registration before coming to the lab?

If you’re coming from a Rush Oak Park Hospital or Rush Oak Park Physicians’ Group physician’s appointment on that same day, you can bypass registration and come directly to the lab. Otherwise, please stop by Outpatient Registration first. It’s located in the building that connects the hospital to the Medical Office Building.

Do I have to have a physician’s order to come to the lab?

Yes. If your physician has placed the order through the EPIC medical records system, you don’t need to bring a paper copy.

Do I have to fast for a Hemoglobin A1C test?

No fasting is required for this test.

Can I drink water if I’m fasting before a test?

Yes — you can always drink water before coming for a test. It’s important to stay hydrated!

How long do I have to fast before a lipid panel?

Fasting for 8–12 hours is recommended.
