Sleep studies are performed at hospital-based sleep labs, independent sleep clinics, and increasingly at home using portable testing kits. The right option for you depends on your symptoms, whether you have other medical conditions, and what your insurance covers. Most people start by getting a referral from their primary care doctor, though some telehealth services now streamline the process significantly.
Hospital Sleep Labs and Independent Clinics
The most comprehensive sleep study, called polysomnography, takes place overnight in a dedicated facility. These facilities fall into two main categories: hospital-affiliated sleep labs and freestanding independent clinics. Both types monitor your brain waves, eye movements, heart rhythm, and breathing patterns while you sleep, but they differ in setting and sometimes in the range of conditions they can diagnose.
Hospital-based sleep labs are typically part of a larger medical center and have immediate access to other specialists if something unexpected comes up during your study. They’re a good fit if you have cardiovascular disease, respiratory conditions, or other complicating health issues alongside your sleep complaints. University medical centers often run research-active sleep programs, which can mean access to newer diagnostic approaches.
Independent sleep clinics and freestanding sleep centers operate outside of hospitals, sometimes as part of a pulmonologist’s or sleep specialist’s office. These tend to feel less clinical and may offer more flexible scheduling, including weekend appointments. For insurance purposes, freestanding facilities generally need accreditation from the American Academy of Sleep Medicine (AASM) or the Joint Commission. You can verify whether a facility near you holds AASM accreditation through the free directory on the AASM website.
Home Sleep Studies
If your doctor suspects you have moderate to severe obstructive sleep apnea without other complicating conditions, a home sleep test may be all you need. These portable kits track your breathing, oxygen levels, and heart rate for one night in your own bed. You either pick up the device from a clinic or have it shipped to you, wear it overnight, then return it by mail or in person.
Home tests cost significantly less than in-lab studies. Typical prices range from $150 to $1,000, compared to $1,000 to $10,000 for an in-lab polysomnography (with an average around $3,000 for in-lab). The tradeoff is that home tests measure fewer variables and can miss certain conditions. If a home test comes back negative or inconclusive but your symptoms strongly suggest sleep apnea, your doctor will generally recommend a full in-lab study as a follow-up.
Home testing is not appropriate for everyone. People with cardiovascular or respiratory disease, those on opioids, anyone with severe insomnia, or those suspected of having conditions beyond obstructive sleep apnea (like central sleep apnea or narcolepsy) need the more detailed monitoring that only an in-lab study provides.
Telehealth Sleep Services
Several major health systems now offer sleep medicine through telehealth. UPMC’s Sleep Medicine Center, for example, conducts first-time consultations and follow-up care entirely by video, then ships a home sleep study kit to your door. After completing the study, you mail the equipment back and review results with your provider remotely. This model works well if you live far from a sleep center or have difficulty taking time off for appointments.
A number of smaller telehealth-first companies also offer this ship-to-home model, though you should confirm that any service you use is working with board-certified sleep medicine physicians and AASM-accredited facilities for study interpretation.
Pediatric Sleep Centers
Children who need sleep studies should be tested at a pediatric sleep center rather than an adult facility. Pediatric labs use age-appropriate equipment and are staffed by technicians trained to work with kids. These centers also typically include behavioral sleep psychologists who can address issues like bedtime resistance or night terrors that wouldn’t show up on a standard sleep study. Only a handful of pediatric sleep centers in the country hold specific accreditation for children’s sleep care, so it’s worth confirming a facility’s pediatric credentials before scheduling.
How to Get a Referral
You’ll need a referral from a physician to schedule a sleep study, and many insurance plans also require prior authorization. Your primary care doctor can order the study directly, or they can refer you to a sleep specialist (usually a pulmonologist or neurologist with sleep medicine training) for an evaluation first. If your primary care doctor orders the study themselves, they typically manage your treatment going forward. If a sleep specialist orders it, that specialist usually handles the results and treatment plan.
When requesting a referral, expect your doctor or insurance company to ask for your specific sleep-related symptoms, how long you’ve had them, and any other health conditions that might be relevant. Medicare covers sleep studies when you show clinical signs and symptoms of sleep apnea. Private insurers have similar requirements but vary in which facilities they’ll cover, so check your plan’s network before booking.
What to Expect the Night Of
For an in-lab study, you’ll arrive in the evening, usually between 7 and 9 p.m. A technician attaches small sensors to your scalp, face, chest, and legs. The wires are long enough that you can move and turn over normally. Most people take 15 to 45 minutes longer than usual to fall asleep in the lab, and technicians account for that. You’re typically free to leave by 6 a.m.
In the days leading up to your study, avoid sleeping medication, alcohol, and caffeine, as all three can alter your sleep patterns and skew results. Bring comfortable pajamas and anything you’d normally use in your bedtime routine. The room will look more like a basic hotel room than a hospital ward, with a regular bed, dim lighting, and a television.
For a home study, the setup is simpler. You’ll wear a small device, usually a belt or clip, that tracks breathing effort, airflow, and blood oxygen. Instructions come with the kit, and most people find it easy to manage on their own. Results from either type of study are typically available within one to two weeks.
