Multiple Sleep Latency Test

Multiple Sleep Latency Test, or Daytime Sleep Study

During the multiple sleep latency test, health-care providers monitor the activity of your brain, eyes, chin and heart throughout the course of four or five pre-scheduled 20-minute sleep opportunities. These test measure how sleepy you are and what kind of sleep you have a certain times during a day.

In order to obtain the most useful findings, you must allow at least eight hours in bed for sleep on a regular schedule for the two weeks preceding this test. In addition, you should adhere to any recommendation from your sleep physician concerning medication that should be discontinued prior to this study.

If you are taking any medications (including over-the-counter and/or herbal supplements), please do not consume them the morning of the study. Please bring your labeled medications with you to discuss whether they should be taken prior to sleep testing if you are uncertain.

Prior to arrival, please eat a normal breakfast, but do not consume caffeinated beverages (coffee, tea, cocoa, colas). If the test occurs the day after an overnight study, breakfast will be provided. Lunch will also be provided for all studies. If you require snacks (for conditions such as diabetes), please bring them with you.

Your hair should be clean (no hairspray, gel or other products, please) in order to minimize interference with data recording.
Wear loose, comfortable clothing. You may bring your own pillow.

You will be in a private room with a television, telephone, and a bathroom with a shower. Please bring a book or magazine to read or something work on between the tests. In order to obtain the most accurate results, we discourage visitors and telephone calls during this time.

Please do not hesitate to call 206.744.4999 if you have any questions.
