Pediatric Multiple Sleep Latency Testing

The multiple sleep latency testing (MSLT) is done immediately following the overnight sleep study and is used to evaluate the degree of daytime sleepiness your child is experiencing.

After your child wakes up, we'll remove some of the sensors and give your child time to relax, eat breakfast, etc. The test consists of five naps scheduled throughout the day separated by 2-hour breaks.

If your overnight study shows evidence of a sleep disorder, your MSLT may be canceled or shortened. Your referring provider should have the results of your sleep studies in two to three weeks.

Instructions for Parents

Please bring the following items:

  • Child's sleep journal filled out for 2 weeks (a regular sleep-wake schedule is important to have in place prior to the test)
  • Comfortable, loose fitting clothes 
  • Entertainment items (books, magazines, DVDs, laptop/tablets, crafts, etc.)
  • Breakfast, lunch, and snacks (we don't have a cafeteria on-site, but we do have a refrigerator for food storage)
  • Toiletries (toothbrush, toothpaste, lotion, etc.)

Important Notes

  • Certain medications can affect the MSLT. If your physician or the sleep lab has asked you to stop taking certain medications, be sure to stop them in time for the test. 
  • No caffeine is allowed during the day of the MSLT.
    • A urine screen will be collected the morning of the study.
