24-Hour Urine 5-HIAA Test for Serotonin Metabolism & Neuroendocrine Health
The 24-Hour Urine 5-HIAA (5-Hydroxyindoleacetic Acid) Test measures the amount of 5-HIAA, a breakdown product of serotonin, excreted in urine over a full day. Elevated or abnormal levels can indicate neuroendocrine tumors (such as carcinoid tumors) or serotonin metabolism disorders. This test provides valuable insights for healthcare providers to assess neuroendocrine function, detect potential tumors early, and guide appropriate treatment and monitoring strategies.
