How to request a lab test

Your health and healthcare are exactly that: yours.

If you think you need a lab test or preventative screening—based on family history, lifestyle, an article you read, or any other reason—don’t put it off. Getting tested is about gaining the information you need to make the health decisions that are right for you.

Start with calling your doctor’s office

Because of regulations in every state except Arizona, patients must have their doctor request lab tests. To get tested, you’ll need to contact your doctor and find out your options for getting a lab order through him or her.


Understand your coverage

Knowing your coverage before your doctor’s appointment will help you know if a test he or she suggests is covered. If a test isn’t covered by your insurance, we may be able to provide you financial assistance and still get you the test you need through one of our more than 2,200 Patient Service Centers nationwide.


Don’t be afraid to ask

Discuss your testing questions with your doctor. No matter how well she or he may know you, ultimately you know you best. Ask with confidence if you’re curious about a particular test. You have a right to know.


Call ahead

Phone your doctor’s office before your next exam, to find out if a particular test is offered as part of a routine checkup. Ask if your specimen can be collected in the office or if you must go to a testing center.

In some instances, he or she may ask you to get a test in advance so your results will be available at your office visit. Or he or she may want to investigate it further or talk with colleagues before ordering the test.


Come prepared

Before meeting with your doctor, it’s a good idea to print out a copy of a related Quest brochure or webpage that describes the test or health condition. If you and your doctor feel that a test is right for you, you might be able to have it done immediately at his or her clinic or at a nearby Quest Diagnostics Patient Service Center.
