The Multiple Sleep Latency Testing, often referred to as a nap study, is used to report on excessive daytime sleepiness and aids in diagnosing narcolepsy or idiopathic hypersomnia.

The MSLT is performed in the sleep lab after a normal night of sleep.

During the MSLT, you will be given 4 – 5 opportunities to nap in 2-hour intervals.  The sleep technician will monitor how long it takes for you to fall asleep each time as well as how quickly you reach REM sleep.

Preparation for an MSLT is the same as the Polysomnogram.

Expect Arrival time to be between 8am – 9am.  Confirmation of time will occur when an appointment is made.

Departure time will be between 4:30pm and 5:30pm.

The technician will compile the data and provide the report to your Certified Sleep Physician.

The report will be analyzed, and results given at your MSLT follow up visit.
