Why This Biomarker Matters

Abnormal homovanillate levels can indicate rare but serious conditions like neuroendocrine tumors. Early detection allows timely intervention and prevents life-threatening complications.

Overview

Homovanillate is a metabolite of dopamine, a neurotransmitter involved in movement, mood, and reward. A 24-hour urine homovanillate test measures dopamine metabolism. Elevated levels may indicate neuroendocrine tumors (like pheochromocytoma), while decreased levels can suggest neurological disorders. This test is valuable for diagnosing catecholamine-secreting tumors and assessing dopamine-related metabolic disorders.
