Why This Biomarker Matters

Abnormal dopamine levels help diagnose rare tumors (pheochromocytoma) and neurological disorders. Results guide treatment for conditions affecting mood, movement, and hormone balance.

Overview

Dopamine is a neurotransmitter and hormone involved in mood, motivation, and movement. A 24-hour urine dopamine test measures dopamine metabolites excreted over a full day. Elevated dopamine levels may indicate a pheochromocytoma (rare adrenal tumor), while low levels can suggest Parkinson's disease or other neurological conditions. This test helps diagnose hormonal and neurological disorders.
