Multiple Sleep Latency Test

(This procedure/test may also be known as: MSLT)

A multiple sleep latency test is a series of nap studies (4-5) which is performed following an overnight sleep study or polysomnography.

The first nap will begin approximately 2-3 hours after being awakened from the sleep study. Each nap lasts 20-35 minutes. There will be 2 hours separating each nap. You should expect the testing to be finished no later than 3 p.m.

Between naps, your child is not allowed to fall asleep, lie down or sit in bed.

Reminders for day of test:

• Complete the 2-week sleep log and bring it with you.
• Bring clothes your child can wear during the day.
• Bring your child's normal medications.
• Bring toys, books, movies, puzzles, etc., to occupy your child between naps.
