Distribution of Homovanillic Acid in the Human Brain
Nature, 1964HOMOVANILLIC acid (3-methoxy-4-hydroxyphenylacetic acid, HVA) is formed by the action of the enzymes monoamine oxidase and catechol-O-methyl-transferase as a final product of dopamine metabolism, and its occurrence in urine has been described1–6. From other investigations7,8 it may be concluded that in experimental conditions the HVA level in the brain

Tardive dyskinesia and plasma homovanillic acid.
Biological psychiatry, 1984Using 61 patients with tardive dyskinesia (TD) and 25 normal controls, we explored the possibility that plasma HVA may reflect alterations in central dopamine activity or clinical aspects of TD. There were no significant differences between the two groups in plasma HVA level.

Determination of Urinary Homovanillic Acid Using the Nitrosonaphthol Reaction
American Journal of Clinical Pathology, 1987Determination of urinary homovanillic acid (HVA) is an important analysis to establish the diagnosis and prognosis of neuroblastoma. A method is presented for the determination of this metabolite of dopamine using its reaction with 1-nitroso-2-naphthol and nitrous acid.
