Which hormones are measured in 24-hour urine testing?

The measurement of various hormones and chemical compounds in 24-hour urine testing is essential for evaluating multiple aspects of endocrine function and metabolic processes in the body. This type of testing captures a complete picture of hormone production over a full day, providing valuable insights that a single urine sample might not offer.

For example, hormones like cortisol are often measured to assess adrenal function and detect conditions such as Cushing's syndrome or Addison's disease. Similarly, 24-hour urine samples can provide information about the excretion of other hormones such as catecholamines, which are relevant in diagnosing pheochromocytoma and other conditions. Additionally, the test can measure metabolites and electrolytes that reflect overall hormonal activity and balance.

Other hormone-related tests, such as for insulin, glucagon, or thyroid hormones, typically rely on specific blood tests rather than urine analysis for accurate assessments. Therefore, the most comprehensive and appropriate answer for what is measured in 24-hour urine testing is the broad category of various hormones and chemical compounds.
