Lab Services



*The Autonomic Function Lab is involved in providing patient care services to many of the clinical disciplines since 1989. Till date the lab is credited to have tested over 6,000 patients from Neurology, Gastroenterology, Endocrinology, Medicine, Orthopaedics, IRCH, Paediatrics and others. Autonomic Function Tests provide an important investigative tool for the diagnosis, prognosis and management of many diseases. The lab routinely tests 3-4 patients daily and also offers services for both basic and clinical research. Currently this lab is fully equipped with sophisticated instruments to conduct vascular function tests. This lab is also conducting clinical research on various diseases and treatment modalities.

Patients are generally referred for Autonomic Function Tests from the OPDs or Clinical wards. They are required to get a date for the tests from the lab and they are also given proper instructions.
