Digestive System Tests

The digestive system, also known as the gastrointestinal system, is a complex set of organs that transport and process the food we eat and transform it into energy for our metabolism to consume. Digestive system tests can help determine whether or not this essential system is working properly and diagnose problems or gastrointestinal disorders of the pancreas, intestine, colon and liver.
