Diagnostic Tests

When you come to us for help, we ask you to complete a survey, such as the Epworth Sleepiness Scale (ESS) questionnaire, that helps determine which additional studies are appropriate for you. You may be asked to spend the night at the center where our specially trained staff perform an overnight sleep study. Our sleep physicians use the following studies to evaluate sleep disorders:

  • Polysomnogram
    An overnight sleep study to observe and monitor your breathing, heart rate and oxygen level during sleep.
  • Multiple sleep latency test (MSLT)
    A daytime study that measures the speed of falling asleep. This test is used to assist in diagnosing narcolepsy and to access daytime sleepiness.
  • Nasal continuous positive airway pressure (CPAP) titration
    An overnight study to determine the effective level of air pressure to maintain an open airway.
