Multiple Sleep Latency Test (MSLT)

Multiple Sleep Latency Test (MSLT)

  • You will be required to complete a nocturnal sleep study in our facility the night before your MSLT (or MWT). Be prepared to submit a urine drug screen on the day of the test.
  • You will be awakened from your nighttime sleep study at 6:00am.
  • The technician will disconnect the wires that will not be used for the MSLT/MWT, though some wires will remain.
  • You will be requested to change into street clothes. This can be anything you are comfortable in, i.e.: shorts, blue jeans, sweats. It is recommended you bring a button up shirt for the daytime MSLT/MWT portion of the study, so wires are not pulled off of your head.
  • You are welcome to bring snack and drinks; we have a refrigerator and microwave. CAFFEINE IS NOT ALLOWED DURING THE DAY. Breakfast and lunch will be provided at no cost to you. If you are on a specialized diet please let us know as soon as possible so we may accommodate your dietary needs inasmuch as we are able. Typically “fast food” is ordered from local restaurants.
  • The test consists of a series of five of nap periods, or testing periods, occurring at two hour intervals, the first of which will begin two hours after awakening. The nap periods are scheduled for 8:00am, 10:00am, 12:00pm, 2:00pm and 4:00pm, and will last approximately 15 to 25 minutes each.
  • In most cases you will be discharged from the lab between 4:30 and 5:00pm. If you have transportation needs, please be sure to pre-arrange them accordingly.
  • You are encouraged to bring books, movies, personal laptop, tablet or anything to help keep you awake and occupied between nap periods. A television, DVD player and WiFi are available.
  • If you are a smoker, you will be permitted to smoke outside between nap periods, but not within 30 minutes of a nap period.
  • If you take any stimulant-type medication, i.e.: Provigil, Ritalin, etc., please inform the staff at time of scheduling, or as soon as possible after your appointment is made, as you may be required to stop taking this medication for a period of time (typically two weeks) prior to your test.
  • Please do contact the clinic staff, or the sleep center supervisor with any questions or concerns regarding your sleep study.
