What is an MSLT?

The multiple sleep latency test (MSLT) is often done following a routine in-office sleep study / polysomnography. The test provides a patient with several opportunities to nap throughout one day. The test is most commonly used to evaluate daytime sleepiness in a patient, measured by the average time it takes the patient to fall asleep during the exam period.

Why is an MSLT used?

The following are the most common reasons for undergoing a multiple sleep latency test:

  • To measure daytime sleepiness
  • To determine the severity of sleep apnea
  • To gauge a patient’s response to his/her current sleep apnea treatment

What does multiple sleep latency testing involve?

At the eos sleep diagnostics NYC sleep testing facility, patients are given 4-5 scheduled opportunities to nap throughout the day in a comfortable, private setting. Patients are comfortable and relaxed during the testing, and can nap as if they were in their own bed.

Afterwards, the mean latency to sleep onset for all naps is calculated and gives a measure of the patient’s daytime sleepiness. After the napping sessions, patients are able to return to their normal daily activities and generally return for results and possible treatment options in the following weeks.

What are the benefits of undergoing an MSLT?
