Even though sleep requirements vary by individual, it is advisable for adults to get at least seven to eight hours of sleep each night. It enhances both physical and mental health. Despite this, most people do not get enough sleep. While lifestyle factors such as work, family, and social obligations can disrupt sleep, underlying sleep disorders are often the root cause. Those who feel they may have a sleep disorder should seek medical attention, and taking a sleep diagnostic test is often the most effective first step toward identifying the issue and finding a suitable treatment.
In this blog article, we will explore the various types of sleep diagnostic tests and how to select one that will work best for you.
Types of Sleep Diagnostic Tests
- Polysomnography Test
A polysomnography test is recommended for individuals who may be experiencing Obstructive Sleep Apnea. It aids in determining whether the patient has this condition, allowing treatment to begin. The sleep test is performed in a lab or hospital overnight. The polysomnography test monitors the sleep cycle and stages of the patient to detect anomalies. During the study, medical equipment is attached to the body to collect data on the brain, respiration, and muscle activities.
- Home Sleep Test
A home sleep test is the ideal sleep diagnostic test for patients experiencing obstructive sleep apnea but who are unable to schedule a polysomnography test due to a lack of slots or the lab’s distance. An HST is a simple and easy way to determine if you have a sleep disorder from the comfort of your own home. The test produces accurate findings, and the necessary equipment is delivered to and picked up from your home. It determines whether you have sleep apnea by measuring your breathing, oxygen levels, and respiratory efforts.
- Multiple Sleep Latency Test
Anyone who experiences severe daytime sleepiness should take a Multiple Sleep Latency Test (MSLT). The study measures how quickly a person falls asleep during the daytime, providing valuable insights into their sleep patterns. MSLTs span an entire day and consist of five tests that are scheduled two hours apart. The patient undergoing the test lies in a peaceful setting and waits to fall asleep. The study assesses how soon one can drift off once the lights go out. If the patient does not fall asleep after 15 minutes, the trial will come to an end.
- CPAP Titration Test
This sleep diagnostic test is intended for patients who have been prescribed Continuous Positive Airway Pressure (CPAP) therapy to treat conditions such as obstructive sleep apnea, central sleep apnea, or hypoventilation. A titration sleep study is performed in a sleep lab overnight prior to starting long-term treatment. The patient’s breathing is monitored throughout the procedure, and CPAP adjustments are made as needed. The healthcare professional will monitor oxygen levels, heart rate, brainwaves, arm and leg movements, and respiration using this sleep diagnostic device. The air pressure is then remotely adjusted throughout the night to discover the optimal range for effective sleep apnea treatment.
- Split-Night Study
A split study is a diagnostic option for patients with severe sleep apnea. This test combines polysomnography and CPAP titration into a single overnight session. The patient receives a sleep apnea diagnosis in the first half, and in the second half, the optimal CPAP air pressure is determined. The split night study minimises treatment time while saving the patient from the hassle of returning on another night.
- Maintenance of Wakefulness Test
In contrast to most sleep diagnostic tests that analyse the patient’s condition by putting them to sleep, this test requires the individual to remain awake throughout the procedure. The study is performed over a whole day and examines the patient’s alertness during the daytime. During MWT, four forty-minute trials are held, and they track how long the participant in the study can stay awake in a calm, quiet, and stimulation-free setting.
How to Select a Sleep Diagnostic Test?
Here are some variables to consider when choosing a sleep diagnostic test.
- Suspected Sleep Disorder
If your doctor believes you have sleep apnea, conducting a home sleep study may suffice. However, a lab test may be required for other sleep disorders.
- Comfort Level
A home test may be a preferable option if you are concerned about sleeping away from home.
- Cost
In general, home tests are less expensive, and this could be a deciding factor if the price is an issue.
- Convenience
If arranging childcare or taking time off work is difficult, a home test may be more convenient.
- The Complexity of the Case
A lab test can be more suitable if you have other medical concerns or your doctor suspects you have several sleep disorders.
