Final answer:
Comprehensive testing of a particular organ system is requested via a panel or profile of tests. This can include blood work, imaging, and more, to provide a thorough examination of that system's functionality, such as the evaluation of the endocrine system by endocrinologists to diagnose conditions like diabetes.
Step-by-step explanation:
When a health care provider requires comprehensive testing of an organ system, they order a panel or a group of tests known as a "panel" or "profile." These tests are designed to assess different aspects of the organ system's function and may include a variety of blood tests, imaging studies, and other diagnostic procedures. For instance, endocrinologists may use such tests to diagnose and manage endocrine disorders. A common panel in this field is a series of blood tests to evaluate the hormonal output of endocrine glands. A classic example is the blood glucose test to diagnose diabetes mellitus, where the patient's response to a glucose challenge gives important insights into pancreatic function. Another test is the A1C, which provides a picture of long-term glucose management by measuring average blood glucose levels over several months. Profiles and panels assist in the monitoring of diseases and the organ systems affected by them, such as the nervous system, circulatory system, digestive system, and immune system, among others.
