The 24-Hour Urine 5-Hydroxyindoleacetic Acid (5-HIAA) test measures the amount of serotonin metabolite excreted in urine over a full day. It plays a crucial role in diagnosing and monitoring carcinoid tumors, serotonin-secreting tumors, and other neuroendocrine disorders. Elevated 5-HIAA levels may indicate excessive serotonin production, helping doctors detect underlying hormonal or metabolic issues early. This non-invasive test provides valuable insights into your body’s serotonin activity, supporting accurate diagnosis and effective treatment planning for optimal health.
