homovanillic acid test
Definition: a test for homovanillic acid based on the fact that dopamine is present in sympathetic nervous tissue as precursor of norepinephrine; because norepinephrine has a metabolic pathway that yields homovanillic acid, some tumors (neuroblastomas and ganglioneuromas may cause elevations in levels of urinary dopamine and homovanillic acid.
