Cortisol, LC/MS (Endocrine Sciences)

This test measures the level of cortisol, a hormone produced by your adrenal glands that helps regulate metabolism and the body's response to stress. It helps show whether your body is making too much or too little of this hormone, which is relevant for investigating symptoms like unexplained weight gain, muscle weakness, or severe fatigue. These results assist doctors in ruling out adrenal gland disorders like Cushing's syndrome or Addison's disease. However, this test cannot identify the specific cause of abnormal levels on its own, as stress, medication, and the time of day also affect results.
