General information, not medical advice. Read our disclaimer.

A sleep study is a test that watches your body while you sleep. It shows what happens to your breathing, oxygen, heart and brain at night. Doctors use it to find sleep apnea and other sleep problems. At Universal Sleep Solutions in Leander, Texas, we do sleep studies in our own sleep lab and at home. Dr. Minal Patel, a board-certified sleep doctor, reads every study.

Which sleep study is right for you?

Your sleep doctor picks the test that fits your symptoms and health. Here are the tests we offer:

  • In-lab sleep study (polysomnography, or PSG) — You sleep one night in our sleep lab. Sensors track your brain waves, breathing, oxygen, heart and leg movements. This is the most complete test.
  • Home sleep apnea test (HSAT) — You wear a small device in your own bed. It checks your breathing and oxygen. It works best for adults who are likely to have sleep apnea and have no other major health problems.
  • Split-night study — One night in the lab that finds sleep apnea and then starts CPAP to find the right air pressure.
  • CPAP titration study — A night in the lab to find the best air pressure for your CPAP machine.
  • MSLT and MWT — Daytime nap tests. They check for narcolepsy and other causes of strong sleepiness during the day.

What happens during an in-lab sleep study?

  1. Check in — You come to the sleep lab in the evening. Bring what you need for bedtime.
  2. Sensors — A sleep technologist puts small sensors on your skin and a belt around your chest. They do not hurt.
  3. Sleep — You sleep in a bedroom at the lab. The technologist watches the readings all night.
  4. Go home — In the morning, the sensors come off and you can leave.

Common questions

Do I need a sleep study to find out if I have sleep apnea?
Yes. A sleep study is the way doctors find out if you have sleep apnea and how strong it is. It can be done in our sleep lab or at home, based on your health and symptoms.
Can I do my sleep study at home?
Many adults can. A home sleep apnea test works best if you are likely to have sleep apnea and have no other major health problems. You can wear the device for up to 3 nights. Some people need an in-lab study instead, such as children and people with heart or lung disease.
Can my doctor refer me for a sleep study?
Yes. Your doctor can fax a referral to (877) 569-2885. You can also pre-register online or call (512) 931-1575.
What happens during a sleep study?
Small sensors are placed on your body. They track brain waves, eye movements, muscle activity, heart rate, breathing and oxygen levels while you sleep. A technologist watches over you all night.
Can I do a sleep study at home?
Yes. Home sleep apnea tests are an option if your doctor thinks you have obstructive sleep apnea. But sleep studies in the lab are more complete, and they are needed for some sleep problems.
How do I prepare for a sleep study?
Do not have caffeine or alcohol on the day of your study. Bring comfortable clothes to sleep in and any medicines you take. Try to keep to your normal sleep schedule.
