• If you would like to speak directly to someone at our third party billing company (not lab test related), they can be reached at 800-311-8590.

• If you would like to speak to directly to an account representative about a bill from Health Labs (the diagnostic company that performs most of our lab test), they can be reached at 630-933-6657. Note, Health Labs is owned by Northwestern Medicine and their primary laboratory is on the Campus of Central DuPage Hospital.
