Diagnostic Laboratory

The GNA Electrodiagnostic Laboratory

Our in-house diagnostic lab is equipped for state-of-the-art testing and reporting, including:

  • EMG
  • NCV
  • EEG
  • Evoked Potentials:
  • Visual Evoked Response (VER)
  • Brainstem Auditory Response (BAER)
  • Somatosensory Evoked Potentials (SEP)

Three of our neurologists have special training to perform EMG studies, one is board certified in EEG and evoked potentials, and our technologists is board certified.

Tests may be scheduled based on the physician's evaluation of the patient. If the doctor prefers, neurologic consultations may be scheduled first, with any of our physicians, to determine the need for electrodiagnostic studies, or to assist the doctor in identifying and treating suspected neurologic conditions.

A dedicated EMG scheduling process assures openings for quick response to physician requests. Most appointments can be made within 3 days of a call, and often same-day scheduling is possible. Reports are mailed and faxed to the physician's office the day following the procedure, and requests for call reports will be honored.
