    According to a study from Rutgers University, an estimated 22 million Americans suffer from sleep apnea and 80% of those with moderate and severe Obstructive Sleep Apnea(OSA) go undiagnosed! Symptoms such as loud snoring, headaches, and feeling tired throughout the day are good indicators you may have sleep apnea. The best way to know for sure is to complete a sleep study. Unfortunately, there’s a lot of confusion between taking an at-home sleep study vs. lab sleep study.

    Keep reading to find out which is best for you and how you can avoid the complexity and wide range of insurance costs commonly associated with traditional lab sleep studies. After all, there’s a good chance you’ll just need to take a simple and affordable home sleep apnea test.

    Today we’ll be discussing the pros and cons of each approach. This includes an analysis of the cost, comfort, diagnostic capability, time commitment, time to treatment, equipment involved, and for whom each test is best. If you’re interested in the home sleep study vs lab sleep study discussion, read on. 

    How To Get Diagnosed With Sleep Apnea

    If you talk to your doctor or health care provider about your sleep health, there’s a good chance they’ll recommend or prescribe an overnight sleep study to further assess your sleep quality. Your two options are to complete a lab sleep study, also known as polysomnography (PSG), or a home sleep study (HST). 

    A lab sleep study is far more comprehensive than a home sleep study, but due to the prevalence of undiagnosed Obstructive Sleep Apnea (OSA) in people without other health complications, an at home sleep test is usually adequate for the majority of those who think they may have sleep apnea.

    Traditional polysomnography has been the standard approach since the late-eighties to mid-nineties, but with advancement in technology, home sleep apnea tests are an increasingly viable (and convenient) option for diagnosing Obstructive Sleep Apnea.

    Polysomnography (in Lab) Diagnostic Capabilities

    It’s important to know that these tests are not equal in their ability to diagnose certain types of sleep disorders. An in-lab sleep study is a more invasive, yet more comprehensive test that can diagnose a wider range of different sleep disorders (not just sleep apnea) when compared to a home sleep test. Again, if you just want a sleep apnea diagnosis, you may not need an in-lab sleep study.

    Traditional polysomnography records brain waves, breathing effort, heart rate, oxygen levels, and muscle movements during the various stages of sleep. A PSG can diagnose all three types of sleep apnea, REM sleep disorders, sleep-related seizure and movement disorders such as restless leg syndrome, narcolepsy, and insomnia.

    At-Home Sleep Study Diagnostic Capabilities 

    A home sleep test, however, is really only qualified to diagnose Obstructive Sleep Apnea. While this may seem like a bit of a roadblock for those with a more complicated health history, it’s great news for the vast majority of people who are seeking an easy way to test for sleep apnea. The core takeaway here is that a home sleep test is just as capable as a lab sleep test in diagnosing Obstructive Sleep Apnea. 

    The American Academy of Sleep Medicine (AASM) does not recommend using home sleep testing as a general screening method for people who are not at risk for Obstructive Sleep Apnea and don’t display symptoms. However, it’s a great alternative to expensive lab testing for those with employer-mandated sleep apnea screenings, such as commercial truck drivers and some military service members. 

    It is estimated that two-to-nine percent of all adults have OSA. It’s four times more common in men and seven times more common among those who are obese. The HypnoLaus Study further showed that in a cohort of 2,121 participants, 23.4% of women and 49.7% of men showed signs of moderate-to-severe sleep-disordered breathing. Women are also much more likely to develop OSA during menopause.

    Another 2017 meta-analysis of 24 studies estimated the number of people affected by moderate sleep-disordered breathing to be 6% to 17% with older generations being affected by as much as forty-nine percent. Simply put, there are a lot of people out there with undiagnosed OSA that would almost certainly benefit from accessible home sleep testing.

    How To Choose Between Home Sleep Study and In-Lab

    An in-lab sleep study should only be used when necessary and for people who absolutely need it. Certain authorities, such as the Department of Transportation, require specific workers (such as commercial truck drivers) to be annually screened for sleep apnea. 

    If you or your health care provider suspect that you are at risk for Obstructive Sleep Apnea and you do not have any previous or underlying health conditions, then congratulations! You’re most likely eligible for a home sleep study. 

    If, however, you have a history of significant heart or lung disease, a neuromuscular condition such as ALS or MS, stroke, chronic opioid use, or pre-existing significant sleep disorders, you’ll have to do a sleep study in the lab for the most comprehensive diagnosis. 

    Understanding The Key Differences in Sleep Testing Equipment

    What makes or breaks the sleep testing experience for a lot of people is the equipment used for the test. It’s what makes a PSG so much more comprehensive than an HST—though not all HSTs use the same equipment. 

    While undergoing a sleep study in a lab, you can expect to be hooked up to several electrodes attached to your chest, stomach, legs, scalp, and various points on your face. You may also be equipped with a nasal cannula, chest belt to measure breath volume and frequency, and a pulse oximeter on one finger. 

    Home sleep testing equipment has come a very long way in the last decade, and there are a variety of options available for home testing. Typically, you’ll have a chest belt, pulse oximeter, nasal cannula, and chest electrode. 

    The more technology advances, however, the more minimalist a home test can be. The SleepAgain Home Sleep Apnea Diagnosis is a fantastic example. This particular HST only uses a small finger attachment, similar to a pulse oximeter, for one of the most minimalist home sleep test experiences available.

    At Home Sleep Study vs Lab Sleep Study Cost

    In this discussion of home sleep study vs lab sleep study, we’ve established that these tests are not made equally and have different target audiences. Perhaps the clearest example of this difference is in the cost of the tests themselves. 

    For many, the cost of an overnight sleep study is going to be the determining factor in whether or not they decide to participate. Using FAIR Health Consumer, we looked at the average pricing for an in-lab sleep study for five of the most populated United States cities and five smaller and more secluded cities, as evidenced by the table below:

    CityZIP Code TestedOut of NetworkIn-Network
    San Antonio, Texas78250$14,933$7,367
    Knoxville, Tennessee37922$10,766$5,222

    Gainesville, Florida32608$4,599$2,175
    Average Cost:$8,738$4,439

    *Please Note: Tested zip code was determined by highest population.

    Despite insurance coverage, the cost of a lab sleep study in a modern setting still averages around $4,500 out of pocket in the United States with the potential to pay upwards of $15,000 without insurance coverage. 

    In stark contrast, you would be hard-pressed to find a home sleep apnea test that costs more than $200, regardless of your insurance policy. 

    You can use the FAIR Health tool to learn more about the average cost of participating in a lab sleep study in a sleep center near you. We used CPT code 95810 for testing purposes, but there are multiple options for sleep testing within the tool for a more clear comparison of what’s available. 

    Want The Most Comfortable Experience? Home Sleep Studies Are the Clear Winner 

    Another area that poses a significant difference in experience is the level of comfort you might enjoy during an at-home sleep study vs in-lab polysomnography.

    On the home sleep test side of things, most tests are designed to be minimally invasive to provide a non-intrusive experience that allows for better sleep quality. You’ll be sleeping in your own bed—an environment that you’re familiar with, comfortable with, and most importantly, accustomed to falling asleep in. 

    In terms of lab sleep studies, the sheer amount of sensors and equipment will almost certainly affect your sleep quality. Factor in sleeping in an unfamiliar environment under observation by a sleep technologist and you have the perfect recipe for fragmented sleep. 

    For these reasons, sleep centers have come a long way in terms of comfort. A good sleep center will put effort into making the testing environment as comfortable as possible. 

    While it won’t compare to sleeping in your own bed with far fewer attachments (especially if you’re considering the minimalist SleepAgain device), you can expect that a sleep center will feel less like spending the night in a hospital bed and more like sleeping in a hotel room. 

    How Long Does a Home Sleep Study Take vs In-Lab?

    While you’ll typically spend one to three nights participating in either a lab or a home sleep study, there are some key differences to be aware of. 

    As a general rule of thumb, one night of recorded sleep does not necessarily paint a full picture of your sleep health or average Apnea-Hypopnea Index (AHI), as evidenced by this 2012 study of multi-night polysomnography. With all of the extra equipment in-lab, it will be difficult for you to attain the same level of sleep quality you can expect at home—not impossible but difficult. 

    It’s also worth noting that you may be asked to return for a CPAP titration study in the event you’re indicated as a candidate for CPAP therapy, though some people also undergo titration on their first night. In a titration study, you’ll also be hooked up to a CPAP machine, and your sleep technologist will test a range of pressures while you sleep to determine which pressure is best for you. 

    Since most home sleep studies prescribe APAP machines, a titration study is not required, and due to the minimal nature of most home sleep studies, you typically only need one night for good results. Some companies prefer to use a three-night average for a more comprehensive result, but many accomplish their goals in a single night. 

    How Long Does It Take To Get Results From a Sleep Apnea Test?

    Finally, we have the average time you can expect to wait before you receive your sleep apnea test results

    Home sleep testing is the absolute and clear winner here. Most home sleep tests promise a turnaround time of less than a week, with some promising a diagnosis in as little as two days! 

    Once you’ve received your diagnosis and decided what route to take in acquiring your PAP equipment (assuming you were diagnosed with OSA), you shouldn’t be more than a few weeks out from the start of your sleep apnea therapy. 

    As a bonus, opting into an at-home sleep study—assuming you meet the criteria—can even help those that truly need lab sleep studies by reducing demand on local clinics and shortening wait times.

    Getting into a sleep lab, on the other hand, can be surprisingly difficult. Sleep labs typically have long waiting periods, which can be very stressful for those seeking diagnosis for more serious health concerns. It’s not uncommon to have to wait six to eight weeks, or even longer, just to get into a sleep lab. 

    On top of this, it could take two to six weeks for you to hear back from your provider after they’ve reviewed your results, putting you behind yet another few weeks as you wait on your equipment to arrive. 

    All said and done, home testing is king when it comes to quick results and overall time to getting relief from Obstructive Sleep Apnea if you don’t have other underlying health conditions. 

    The Bottom Line

    There are pros and cons to each type of sleep study, so hopefully you now have a better understanding of which one might better suit your needs. While not created equal, there are major benefits to being tested—period. If you’ve been told repeatedly that you’re a loud snorer, are constantly fatigued during the day, or never seem to wake up feeling refreshed, it might be better safe than sorry to book a consultation with our telemedicine partner today to discuss your options for home sleep apnea testing!
