Multiple Sleep Latency Test (MSLT) Instructions

The Multiple Sleep Latency Test is a series of nap studies that will be performed following your child's overnight sleep study or PSG. The MSLT is conducted in the sleep lab.

In order for the study to be as accurate as possible, please follow these instructions for the day of the study.

  • One parent/guardian is expected to stay with the patient throughout the MSLT, although the parent/guardian will be permitted to walk around the hospital, if needed.
  • Keep healthy sleep habits for one week before the test -- no late night events, sleepovers, etc.
  • The doctor ordering the test may ask you to stop some medications before the test. Bring all medications with you.
  • Complete a sleep log for two weeks up to and including the day of testing and bring it with you to give to the technician.
  • Bring clothes for your child to wear during the day. 
  • Naps will be every 2 hours for 30 minutes and patients must stay awake between naps.
  • Bring homework, toys, books, movies, puzzles, etc., to occupy your child between naps.
  • Breakfast & lunch will be provided for patient only. A refrigerator and microwave are available in the sleep lab.
