Sleep tests are used to diagnose sleep disorders such as sleep apnea, periodic limb movement disorder, narcolepsy, restless legs syndrome, insomnia, and REM sleep behavior disorder. To schedule a sleep study, you will typically need a referral from a physician, and in some cases, authorization from your health insurance company. This referral can come from your primary care physician, a specialist, or your dentist. In some cases, patients with straightforward medical conditions can be directly scheduled for a sleep study without needing to be seen in the Sleep Clinic first. However, it is always best to consult with a physician first to determine the best course of action.

What You'll Learn
Sleep tests can be done at home or in a lab
Home Sleep Tests
Home sleep tests are a simplified version of lab-based sleep tests. They are typically used to assess obstructive sleep apnea, a common sleep disorder characterised by interrupted breathing during sleep. Home tests are often recommended for patients who are generally healthy. This is because certain medical conditions, such as congestive heart failure, obesity, and chronic obstructive pulmonary disease (COPD), can affect the results of home testing.
Home sleep tests are usually carried out over one night and involve placing sensors on your body to monitor your breathing, oxygen levels, and heart rate. They are more convenient and cost-effective than in-lab tests, and you can do them in the comfort of your own bed. However, they don't capture as much data as in-lab tests and are not as accurate. Home tests may also be inappropriate or inconclusive for people with other sleep disorders, such as narcolepsy, insomnia, or restless leg syndrome.
In-Lab Sleep Tests
In-lab sleep tests are conducted in a sleep lab or clinic and involve placing sensors on your head, face, chest, and limbs to monitor a range of factors, including breathing, muscle and eye movements, brain wave changes, oxygen levels, blood pressure, and heart activity. These tests are more comprehensive than home tests and can be used to diagnose a wider range of sleep disorders, such as obstructive sleep apnea, central sleep apnea, narcolepsy, and periodic limb movement disorders.
In-lab tests are generally more accurate than home tests, and they allow for a more thorough assessment of sleep issues. They are attended by a sleep technologist who can monitor you throughout the test. However, in-lab tests can be more expensive and may interfere with your sleep due to the unfamiliar surroundings.
Both home and in-lab sleep tests have their advantages and disadvantages. Home tests are more convenient and cost-effective but are less comprehensive and accurate. In-lab tests provide a more detailed assessment but can be more expensive and may require additional travel. It's important to discuss your options with a medical professional to determine which type of sleep test is most suitable for your specific needs and circumstances.

A doctor's referral is usually required for a sleep test
If you are considering a sleep test, you should consult your doctor, who will be able to refer you to a sleep specialist or sleep lab if they think it is necessary. The sleep specialist will then give you a consultation and decide how to proceed with your diagnosis.
In some cases, a patient may not need a doctor's referral for a sleep test. For example, if you have had two sleep studies in the past 12 months, you may be able to pay for a sleep test yourself or claim from your private insurance company if you have coverage. You can also have a sleep study done in your home at your own cost.
It is important to note that sleep tests can be done in a lab or at home, and each has its own advantages and disadvantages. In-lab sleep studies are more comprehensive and can monitor a variety of functions, including heart rate, breathing, eye movement, brain activity, muscle tone, respiratory effort, airflow, snoring, blood oxygen levels, and body position. On the other hand, home sleep tests are more convenient and can be done in the comfort of your own home, but they only monitor a limited number of functions.
Additionally, insurance companies may have specific requirements for sleep tests, and you may need to meet certain criteria or get approval from your insurance company before scheduling a sleep test.

Sleep tests can help diagnose sleep apnea
A polysomnogram is a multiple-component test that electronically records specific physical activities while you sleep. The recordings are then analyzed by a qualified sleep specialist to determine if you have sleep apnea or another type of sleep disorder. The test equipment includes surface electrodes on your face and scalp, belts around your chest and abdomen to measure breathing, and a bandage-like oximeter probe on your finger to measure blood oxygen levels.
Home sleep tests are a more convenient and cost-effective option for diagnosing sleep apnea. These tests typically involve using a home kit with simple instructions to measure airflow through your mouth and nose, movements in your chest wall, oxygen levels, and heart rate while you sleep. However, home sleep tests are only suitable for people with a high probability of having obstructive sleep apnea (OSA) and no other sleep or medical disorders.
If you suspect you may have sleep apnea, it is important to consult with a medical professional and get a proper diagnosis. Sleep apnea can have serious health consequences if left untreated.

Sleep tests may be covered by insurance
The type of sleep test and the associated costs covered by insurance can vary. Home sleep tests are typically less expensive and may be covered by insurance if certain criteria are met. For example, individuals with a high probability of obstructive sleep apnea (OSA) and no other medical disorders may qualify for a home sleep test covered by insurance. On the other hand, in-lab sleep studies involve more comprehensive monitoring and may be covered by insurance for specific diagnoses or when deemed medically necessary.
It is important to note that insurance coverage for sleep tests can vary depending on the insurance provider and the individual's plan. Therefore, it is always recommended to consult with your insurance company directly to understand their specific requirements and coverage policies for sleep tests. Additionally, some sleep labs or clinics may have financial assistance programs or payment plans to help cover the costs of sleep tests for those without insurance or with limited coverage.
Furthermore, insurance coverage for sleep tests may also depend on the reason for the test. For instance, individuals with suspected sleep apnea may have different coverage requirements than those experiencing insomnia or other sleep disorders. In some cases, insurance companies may require individuals to try more conservative or less invasive treatments before approving coverage for more extensive sleep tests.

Sleep tests are non-invasive
There are several types of sleep studies, each designed to assess different aspects of sleep and diagnose specific disorders. Polysomnography (PSG), considered the gold standard of sleep studies, is typically conducted in a sleep laboratory or hospital setting. It involves monitoring multiple physiological parameters throughout the night to diagnose disorders such as sleep apnea, periodic limb movement disorder, and narcolepsy. The Multiple Sleep Latency Test (MSLT) is a daytime sleep study that measures how quickly a person falls asleep and enters REM sleep during daytime naps, useful in diagnosing conditions like narcolepsy and idiopathic hypersomnia. Home Sleep Apnea Testing (HSAT) is a convenient and cost-effective alternative to in-lab polysomnography, allowing individuals to undergo testing in the comfort of their homes. Actigraphy is a non-invasive method of monitoring human rest/activity cycles over extended periods, typically using a small, wearable device worn on the wrist. Lastly, the Maintenance of Wakefulness Test (MWT) assesses a person's ability to stay awake and alert in a quiet, relaxing environment, useful in evaluating treatments for disorders causing excessive daytime sleepiness.
Sleep studies are typically ordered by a physician, who will refer the patient to a sleep lab or center. In some cases, insurance companies may also require authorization. The sleep study process usually begins with an initial consultation with a sleep specialist, who will evaluate the patient's symptoms and determine the most appropriate type of sleep study. The patient will then undergo the selected sleep study, which may be conducted in a sleep lab or at home, depending on the situation. After the study, a technologist will collect the data, and the patient will schedule a follow-up appointment to discuss the results and determine the next steps for treatment or further diagnosis.
