Home Sleep Apnea Test (HSAT)
A Home Sleep Apnea Test (HSAT)—also known as a home sleep test or at-home sleep study—is a simplified way for patients to be evaluated for obstructive sleep apnea (OSA) in the comfort of their own home. The device records your breathing, oxygen, and heart rate while you sleep, allowing your physician to determine if pauses in breathing are occurring overnight.
Can I do a sleep study at home in Bay City?
Yes. A home sleep apnea test is an overnight sleep study you take in your own bed. A small device records your breathing, oxygen, and heart rate, and a board-certified sleep medicine physician interprets the results. Every home test needs a physician order, and your provider decides whether home testing or an in-lab sleep study is the better fit.
How do I schedule a home sleep test?
Ask your doctor to send an order to our Bay City office using the referral form below, or call us at 989-778-1425. We review your health history and insurance, schedule your test, and show you how to use the device. Return it by the due date and time on your paperwork. Caro patients return it to the McLaren Caro Region hospital main front desk (401 N Hooper St); Thumb patients return it to the McLaren Thumb Region front desk (1100 S. Van Dyke, Bad Axe).
At TriCity Lung & Sleep, we coordinate every step of the process to make it easy for both patients and referring providers. Once your physician determines that a home test is appropriate, our team reviews your medical history and insurance coverage before scheduling your test. We handle the logistics, provide instructions, and ensure the results are interpreted by a board-certified sleep medicine physician in accordance with American Academy of Sleep Medicine (AASM) guidelines.
What to Expect
Most patients are surprised by how easy home testing is. The small monitoring device is typically worn overnight and records airflow, oxygen saturation, respiratory effort, and heart rate. You’ll return the device by the due date and time on your paperwork, and our team reviews the data promptly. Once interpreted, we’ll contact you and your referring provider with the official report and next steps.
Our Role in Your Care

Our staff confirms medical appropriateness, verifies insurance benefits, manages authorizations, and ensures timely communication between all parties.
