Evaluation and Testing

We offer comprehensive evaluation and sleep testing based on referral from your physician.


After you have been referred to us, you will receive a packet of information and questionnaires in the mail along with some general insurance instructions. Once you receive the questionnaire packet, please call the Sleep Disorders Center to make an appointment. Please complete the questionnaires and bring them with you to your appointment.


There are several common tests to diagnose sleep issues:

  • Multiple sleep latency tests (MSLT): Commonly called a "nap study," this test helps determine the severity of excessive sleepiness. This test is performed primarily during the day following your overnight sleep study.
  • Maintenance of wakefulness test (MWT): This test is an alternative to the MSLT. It is the maintenance of wakefulness test. The MWT helps to determine if a person is abnormally sleepy during the day by measuring the individual's ability to stay awake. This test is performed primarily during the day.


Most sleep disorders can be treated or managed effectively once they are accurately diagnosed. Diagnosis and treatment recommendations for sleep disorders are based on the findings of the consultation including the overnight sleep recording.

Typically, for obstructive sleep apnea, one full night sleep evaluation is needed to assess an individual's sleep disorder. Then, if needed, the person returns for a second night for treatment such as continuous positive airway pressure (CPAP).

CPAP is a highly effective treatment for obstructive sleep apnea. A person wears a light mask on their nose, which is attached to a CPAP machine. When the machine is turned on, a steady flow of air enters the sleeper's nose and flows into the airway. The air pressure from the machine then helps prevent snoring and obstructive sleep apnea from occurring by keeping the airway open while the person sleeps.
