Medical Diagnostic Laboratories in Texas

Electromyography & Nerve Conduction Velocity Testing (EMG/NCV)

EMG/NCV diagnostic tests assess the health of the peripheral nervous system. These test results uncover the nature and location of issues such as nerve/muscle dysfunction and failures in nerve-to-muscle signal transmission.

Intraoperative Neurophysiological Monitoring (IONM)

IONM is used in both routine and complex procedures for real-time evaluation of the spinal cord and peripheral nerves. It can also be utilized for pain management treatments, including RFTC and spinal cord stimulator placement.

A Proximity Care Approach

Our proximity care approach is the driving force that sets us apart and positions Principle Health Systems as a leader in diagnostic and laboratory services in the United States. We are uniquely equipped to provide our partner physicians with all the necessary services to help achieve a rapid and accurate diagnosis right on-site.

The comfort and satisfaction of both physicians and patients alike are our top priorities. In addition to our efficient diagnosis services, we also staff a responsive and attentive customer relations team, willing to work alongside you to answer any questions or concerns you may have.
