Homovanillic acid (HVA) is a major catecholamine metabolite that is produced by a consecutive action of monoamine oxidase and catechol-O-methyltransferase on dopamine.^[1] Homovanillic acid is used as a reagent to detect oxidative enzymes, and is associated with dopamine levels in the brain.

In psychiatry and neuroscience, brain and cerebrospinal fluid levels of HVA are measured as a marker of metabolic stress caused by 2-deoxy-D-glucose.^[2] HVA presence supports a diagnosis of neuroblastoma and malignant pheochromocytoma.

Fasting plasma levels of HVA are known to be higher in females than in males.^{[
