5-Hydroxyindole-3-acetic Acid (Cat No.:R042317) is the primary metabolite of serotonin, a neurotransmitter involved in mood regulation, digestion, and sleep. It is produced when serotonin is broken down by the enzyme monoamine oxidase (MAO) and is excreted in urine. Measurement of 5-HIAA levels in urine is commonly used as a diagnostic tool for detecting carcinoid tumors, which secrete large amounts of serotonin. Elevated levels of 5-HIAA can indicate the presence of these tumors, making it a key biomarker in medical diagnostics for neuroendocrine tumors.
