How accurate are the at home sleep apnea tests?
Under these guidelines, both in-lab polysomnography (PSG) and home sleep apnea testing (HSAT) were considered appropriate methods for obtaining diagnosis. According to one multi-center study of 264 patients, the NightOwlTM HSAT scored a 72% accuracy rating, compared to the traditional PSG tests done in sleep labs.
Can you test yourself at home for sleep apnea?
At-home sleep apnea testing is an easy, cost-effective way to figure out whether you're having trouble breathing. A home sleep apnea test is a very simplified breathing monitor that tracks your breathing, oxygen levels, and breathing effort while worn.
What is the best way to test for sleep apnea?
Nocturnal polysomnography. During this test, you're hooked up to equipment that monitors your heart, lung and brain activity, breathing patterns, arm and leg movements, and blood oxygen levels while you sleep.
Can you get a false positive for sleep apnea?
It is possible for a home sleep test to produce a “false-positive result.” About 15 percent of people without OSA are likely to receive a false-positive result. This is even more common in older adults who often have other medical problems or sleep disorders that affect sleep.

It may take a little longer to fall asleep, but usually, you'll get plenty of sleep which will give the clinicians lots of data to work with.
Can a sleep study miss sleep apnea?

Conclusion: Results from home sleep monitoring corre late well with the laborator y "gold standard" and may be an option for diagnosing OSAS in selected patients.
Can you compare a polygraph to a home test?
Aim: There are no studies comparing tests performed at home with those carried out in the laboratory, using the same device. The only studies that have been performed have compared the device used at home with the standard polygraph used in the laboratory. The purpose of this study was therefore to verify the accuracy of the home diagnosis of obstructive sleep apnea syndrome (OSAS) via unassisted type 2 portable polysomnography, compared with polysomnography using the same equipment in a sleep laboratory.
How accurate are sleep apnea tests?
How Accurate Are Home Sleep Apnea Tests? According to Harvard Health, approximately 60 to 70% of sleep tests are now conducted at home. 1 Traditionally, testing for sleep apnea meant spending the night in a sleep lab, connected to wires and waiting weeks for results.
What is total sleep time?
Total Sleep Time (TST): Total sleep time is the total amount of time a patient is asleep. This can be useful when conducting a multi-night study to determine average sleep time. Some devices, such as NightOwl TM will also track REM sleep. REM, or rapid eye movement, is usually considered the dream state. On average, approximately 20-25% of sleep should be spent in the REM stage. 3
How Do I Know If the Results Are Accurate?
Home sleep apnea tests must be interpreted by a board-certified sleep physician. Even though these tests have been approved by the AASM as well as the FDA, there still may be some inaccuracies that occur. For example, if the device is not secure and falls off in the middle of the night, or if an individual attempts to take the test after a night of unusual activity (drinking, smoking, etc.). Some physicians may require multiple nights of testing to see a bigger picture. Devices like the NightOwl TM can be used for up to 10 nights of testing before being disposed of.

While every home sleep test device may measure something different, the majority of them measure the same core data : AHI, pulse rate, SpO 2, and total sleep time (TST).
What is the most accurate test for sleep apnea?
Polysomnography, an overnight sleep study performed in a lab, provides the most accurate diagnosis 5 for obstructive sleep apnea. However, this type of test can be more expensive, and people in certain areas may face long waitlists 6 or lack easy access to a sleep center. At-home sleep apnea tests are designed to make testing more accessible and help ensure people get the treatment they need.
How to get accurate sleep apnea reading?
To ensure a more accurate reading, avoid napping, caffeine, alcohol, and late or heavy meals 12 on the day of the test. Some experts believe it is better to sleep with the portable test equipment for one to three nights to gather enough data. For many people, sleep apnea is worse when back sleeping 13 as opposed to side sleeping. Collecting data over multiple nights and informing your doctor of your habitual sleep positions might help give a more accurate view of your symptoms.
What Is an At-Home Sleep Apnea Test?
A home sleep apnea test is a test that can help diagnose obstructive sleep apnea at home 4. The device itself is a portable breathing monitor you wear overnight. As you sleep, the device monitors your breathing and oxygen levels to detect and measure pauses in breathing, which are known as apneas. The test calculates an OSA severity score by calculating the average number of lapses in breathing per hour in bed.
How does a sleep apnea test work?
When you take a sleep apnea test at home, the machine monitors your breathing once you turn it on. Instead of dividing the total number of respiratory events by your total sleep time, they are divided by the total amount of time you spend in bed, which tends to be longer. As a result, at-home tests can underestimate the severity of sleep apnea by calculating an hourly rate that appears lower than it really is. By contrast, polysomnography is able to record when you are sleeping and when you are awake for a more accurate score.
How many people have OSA?

Sleep tests fall into different categories depending on how accurately they measure different sleep metrics. Home sleep apnea tests are generally classed as level III or level IV. Level III tests use a greater number of sensors to capture relevant information such as blood oxygen levels, airflow, snoring, body position, or heart rate 9. There may be variations between tests, as researchers are still developing new testing kits.
How accurate is sleep apnea test?

Is sleep lab more effective than at home?
Because the sleep lab study gives a more comprehensive picture of your sleep, it is more effective at detecting obstructive sleep apnea than an at-home study. Furthermore, these in-lab tests can diagnose other sleep disorders, including periodic limb movement disorder, REM sleep behavior disorder, and narcolepsy.
Can you get a sleep test at home?
Currently, at-home sleep tests are designed to test for obstructive sleep apnea. These tests are recommended only for people with symptoms that indicate moderate to severe obstructive sleep apnea. Those with a history of cardiorespiratory diseases, stroke, insomnia, or hypoventilation should do their sleep study in a lab and not conduct an at-home sleep test.
What score do you need to take a home test?
A “yes” score of 5 or higher may make a home test appropriate, Kaplish says.
Can OSA be negative?
A home test only measures breathing, not actual sleep, so results can be inconclusive or falsely negative. Patients with OSA often breathe through their mouths, which may lead to inaccurate signals. Although rare, a self-administered device may become loose on the finger at night, too. On the other hand, a comprehensive in-lab test — with sensors to record airflow, respiratory effort, brain waves and many other functions — gathers clinically useful information such as how many times a person wakes up at night and leg movements during sleep.
