What is 24 Hrs Urinary 5 HIAA Hydroxy Indole Acetic Acid?
The 24 Hrs Urinary 5-HIAA test measures the amount of 5-hydroxyindoleacetic acid (5-HIAA), a breakdown product of serotonin, in your urine collected over 24 hours. Serotonin is a chemical produced by certain cells in the body.
Why is this test important?
This test is primarily used to help diagnose and monitor carcinoid tumors, which are rare neuroendocrine tumors that can produce excessive amounts of serotonin. Elevated 5-HIAA levels can indicate the presence or recurrence of these tumors.
