A cortisol test, available for blood evaluates cortisol levels to assess adrenal gland and pituitary gland function, with abnormal results indicating potential disorders or tumors affecting hormone production. Cortisol, known as the "stress hormone," influences various bodily functions, including stress response, inflammation reduction, blood sugar regulation, and blood pressure control, highlighting its significance in overall health assessment. While high cortisol levels may indicate Cushing's syndrome or prolonged steroid use, low levels may suggest Addison's disease or secondary adrenal insufficiency, necessitating further diagnostic tests to pinpoint underlying causes.

Symptoms such as fatigue, weight fluctuations, muscle weakness, and abdominal pain may prompt a cortisol test, aiding in the diagnosis of conditions affecting cortisol levels. The test's methodology varies based on sample type, with blood samples usually collected twice a day to capture fluctuations, while urine and saliva samples may require 24-hour collection or single-time sampling, respectively. Preparations for the test depend on sample type and may involve resting to minimize stress-induced cortisol elevation or adjusting medication usage. While cortisol test results alone may not diagnose conditions definitively, they serve as a valuable tool in conjunction with other tests to assess adrenal function and guide further diagnostic and treatment decisions.
