What is Homovanillic acid (HVA) , 24 Hour Urine?

This test measures Homovanillic Acid (HVA), a breakdown product of the neurotransmitter dopamine, in a urine sample collected over 24 hours. It helps assess the levels of these substances in your body.

Why is this test important?

HVA levels are important for diagnosing and monitoring certain conditions, particularly neuroblastoma and other tumors that produce catecholamines. It can also be used to monitor treatment effectiveness for these conditions.

How to Prepare

A 24-hour urine collection is required. You may need to avoid certain foods (like bananas, citrus fruits, vanilla) and medications before and during the collection period. Follow specific instructions carefully.
