Pre Test Information: Patient should strictly avoid L-Dopa at least 72 hours before and during collection.
Test Details: The Homovanillic Acid (HVA) 24-hour urine test is a medical test used to measure the levels of homovanillic acid in a person’s urine over a 24-hour period. Homovanillic acid is a metabolite of the neurotransmitter dopamine and is produced when dopamine is broken down in the body. This test is often used in the diagnosis and monitoring of certain conditions related to dopamine metabolism, such as neuroblastoma (a type of cancer that typically affects children), pheochromocytoma (a rare tumor that develops in the adrenal glands), and certain types of dopamine-secreting tumors.
To perform the test, the patient is required to collect all urine produced over a 24-hour period in a special container provided by the healthcare provider. The container is typically kept in a cool place during the collection period to prevent the breakdown of homovanillic acid. Once the collection period is complete, the urine sample is sent to a laboratory for analysis. The laboratory measures the concentration of homovanillic acid in the urine and provides a report to the healthcare provider.
Abnormal levels of homovanillic acid in the urine can indicate an underlying condition. High levels may suggest the presence of a dopamine-secreting tumor or neuroblastoma, while low levels may indicate a deficiency in dopamine metabolism.
It is important to note that the HVA 24-hour urine test is just one component of a comprehensive diagnostic evaluation. Additional tests and clinical assessments may be necessary to confirm a diagnosis and guide treatment decisions. It is recommended to consult with a healthcare provider for further information and interpretation of test results.
