Our Policies

Dear Patient:


The test that is being conducted is called a polysomnography.  Due to the nature of this test, results cannot be determined until further analyses and interpretation are completed by one of our physicians.  Please do not ask the technician the results of your study; they're unable to provide you with any information.

Test results will be reported to your doctor’s office 10 – 14 days after your study.


Your assessment and diagnosis is very important to us.  We do understand that changing an appointment is sometimes necessary. If you find that you are unable to make your scheduled appointment, kindly give us 24-hour notice.  If you fail to report for your scheduled sleep study and/or do not call our office to cancel your appointment you will be billed an $80 room fee which your insurance provider will not cover.

Our telephone number is (716) 298-8135 If you are greeted by our answering system, please leave your name and message.

Thank you in advance for your consideration.
