Types of Tests

There are two different types of sleep studies.

  • In lab tests (polysomnograms)
  • Home sleep studies (HST)

In most cases, your insurance covers both types of testing with documentation of medical necessity from your referring doctor or our sleep specialists. In order to complete a sleep test you need a prescription for the test, your most recent office visit notes, and a copy of your demographic information.


There are 80 plus disorders of sleep that range from mild to life-threatening.  In order to diagnose and treat your sleep problem, your primary care or sleep specialist may order a polysomnogram sleep test. This type of test requires an overnight stay at our state-of-the-art sleep centers. You will stay in a private, comfortable room to sleep while a highly trained and licensed sleep/respiratory therapists monitors your breathing patterns, oxygen levels, heart rate and rhythm, and brain waves. This type of test is superior to a home study as it gives the doctor a comprehensive evaluation of how your heart and breathing are affected by your sleep patterns. Talk to your sleep doctor about which test would be better for you and your health!

Home Sleep Apnea Test

Sleep apnea is a serious medical disorder that affects your breathing while you are asleep. This can result in snoring, excessive daytime sleepiness, memory impairment, and even heart disease, stroke and other serious health issues. Some patients are candidates for a home test in which you receive a device to wear at your home to measure your breathing while you sleep.

Patient's Comments on the Experience

"This was nothing like I thought it was going to be.  The center was more like a nice hotel, clean and comfortable with a warm inviting decor.  I was expecting a stark hospital like room.  The attendant took the time to explain everything to me in simple terms making sure I understood what was happening."

--Sara J.

"The only regret I have about this experience is I waited so long to do it.  I have been putting it off for YEARS!  I am getting better sleep and have even moved back into the bedroom with my wife.  My snoring had gotten so bad that I regularly was sleeping in the guest bedroom."

--Marcus L.

"My tech did an excellent job of explaining everything and making me comfortable."

---Kwan K.

"Nothing could be done better.  You have a wonderful comfortable place.  My tech was a joy!"
