Importance of Urinary Drug Screening in the Multiple Sleep Latency Test and Maintenance of Wakefulness Test

摘要

Study Objectives: Multiple sleep latency testing (MSLT) and the maintenance of wakefulness test (MWT) are gold-standard objective tests of daytime sleepiness and alertness; however, there is marked variability in their interpretation and practice. This study aimed to determine the incidence of positive drug screens and their influence on MSLT, MWT, and polysomnographic variables.
