NeuroDiagnostic Laboratories (NDL) at its core began offering neurology diagnostics in an out-patient setting, circa 2002, for the specialists and practitioners who needed them most. The philosophy of NDL was to streamline a procedure from every aspect to the administration, referring physician, and patient. What NDL had concluded was when physicians and patients fail to receive a medically necessary diagnostic study in an efficient timeframe, as well as accurate and concise results, the outcome of the study held less and less value. While in certain cases our diagnostic procedures are no doubt stand alone modalities, it’s the cases that give the referring physicians a new window or different perspective where our value is really recognized. From the inception, NDL has acknowledged the benefit of the neurology consultation in giving direction to the treatment of patients and therefore NDL is pleased to provide them when requested. For the practitioners requesting neurology management, while not provided by NDL, management can be arranged and facilitated through the most qualified and closest proximity neurologist for the patients given situation.
Presently, NDL operates several clinics in the Metro Phoenix area. NDL is in the process of offering additional services to encompass the world of neurophysiology studies. The physicians on staff with NDL are respectively some of the best in their field and since the majority of neurophysiology diagnostics are physician driven, NDL physicians are involved in every aspect to the performance, direction, and interpretation of the procedures. There is a constant development into the techniques and protocol that further our knowledge into the endless endeavor of neurophysiology.
The plans for the future of NDL are to continually build on our relationships with the neurology community and provide critical insight into the direction of patient care. We hope to collaborate on more and more research projects such as helping understand a disease process through our neurophysiology modalities, aggregating data on a specific diagnosis that impacts our society, and monitoring the efficacy and resolve of various treatments.
This is our passion and our commitment.
Yours in Health,
