Explore the Importance of the 24-Hour Urine 5-HIAA Test for Detecting Neuroendocrine Tumors
The 24-Hour Urine 5-HIAA (5-Hydroxyindoleacetic Acid) test is a key diagnostic tool used to evaluate serotonin metabolism and identify carcinoid or neuroendocrine tumors. By measuring 5-HIAA levels in urine collected over 24 hours, this test helps detect abnormal serotonin secretion linked to tumors in the digestive tract or lungs. High levels of 5-HIAA may indicate excessive serotonin activity, guiding doctors toward early diagnosis and effective treatment strategies. Regular testing supports better management of hormonal and metabolic health.
