Sleep apnea, narcolepsy, restless leg syndrome… there are so many disorders that can impact your sleep at night. You’ve done the hard part and identified that something is preventing you from getting the kind of sleep you need—but now you need to narrow it down. You’re ready to dive in and explore the possibilities—but how much will a sleep study cost you?

What king of sleep study do I need to do?

There are a few different types of sleep studies that might benefit you. Your doctor can always help guide you, but here’s an idea of some of the sleep tests that are available.

  • Polysomnography (PSG)
  • Continuous positive airway pressure (CPAP) study
  • Split-night study
  • Multiple Sleep Latency Test


Polysomnography tests are typically the go-to for a sleep apnea concern. This test results in a baseline polysomnogram that measures eye movement, physical movements, airway obstruction, heart rate, and a number of other stats that help put together a full picture of your sleeping patterns.

Continuous positive airway pressure (CPAP) study

A CPAP titration study uses CPAP therapy to attempt to manage symptoms of sleep apnea. A CPAP machine uses a mask to apply constant air pressure to keep the airway from collapsing while you sleep. This prevents breathing issues associated with the different types of sleep apneas. A CPAP study will typically employ a CPAP machine to measure changes to sleep and breathing patterns compared to your baseline.

Split-night study

If sleep apnea is suspected but not confirmed, starting with a typical polysomnography test may cause those administering the study to wake the sleeper up halfway through the night and start a CPAP machine regimen. The second half of the night will measure any improvement so get an official diagnosis.

Multiple Sleep Latency Test

A multiple sleep latency test is used to diagnose other sleep disorders. This test measures how long it takes a patient to fall asleep in a stimulant-free environment, over the course of several scheduled naps throughout the day. This can be used to diagnose narcolepsy. A version of this test can also be done at night, which measures how long it takes to fall asleep in a dim room.

There are other sleep studies that you may be asked to do by your doctor, but typically these are the go-to tests to begin diagnosing a sleep disorder.

Where do I do a sleep study?

Sleep studies can be conducted in a lab, at home, or even a private sleep institute. Where you’re doing these tests can dictate the cost, so pay close attention to where your physician may be sending you.

In lab

Sleep labs are usually in a hospital, but some independent labs do exist. They are usually set up as comfortable as possible to get a realistic baseline of your typical night’s sleep. Even if you aren’t able to fully relax and get as deep as sleep as you normally do, the data collected on your breathing patterns and heart rate can still be super useful in diagnosing potential problems. A tech will set you up with electrode sensors and help if you have any issues throughout the night.

At home

You may be able to complete a sleep study at home if your doctor and insurance cover it. This would typically involve using a CPAP machine or some other device to track your sleeping habits throughout a typical 8 hour night to see any changes in your patterns, breathing, and heart rate. If you are able to book an in home test, this might be the most realistic option, instead of putting yourself in a more clinical, and perhaps stressful situation. Most independent sleep labs also offer at home solutions, and can be worked out through your insurance plan.

So, how much does a sleep study cost?

That can be tough to answer without knowing the details of your individual health insurance plan, but a safe estimate is about $1,000 per night for an overnight study done in a lab. Many health insurance plans cover these costs, but if you do have to pay out of pocket, you can usually work out a payment plan with the sleep center.

Most sleep studies range anywhere from $300 to $3,000 depending on what all you need to be tested for, but that’s just a guideline. Always call your insurance to ask about any medical testing costs up front—and see if you can negotiate a cash discount with the testing lab if possible.

Some sleep disorders can be dangerous, so if you suspect that you do have an issue at night, it’s always better to talk to a doctor and get the necessary testing to determine what’s happening.
