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.Шаблон:Citation needed This does not seem to be influenced by adult hormonal changes, as the pattern is retained in the elderly and post-menopausal as well as transgender people according to their genetic sex, both before and during cross-sex hormone administration.[3] Differences in HVA have also been correlated to tobacco usage, with smokers showing significantly lower amounts of plasma HVA.
