Specimens: 10 ml Urine (u)
Info: Please note that testing ordered for homovanillyl acid and vanillinmandelic acid can only be performed if there is no additional order for katecholamines or metanephrines under this order number.

Acidify 10 ml spot urine with 4-5 drops of approximately 10-20 % hydrochloric acid and mix. Medication interfering with the sympathetic nervous system or the metabolism of catecholamines should be terminated approximately 1 week before testing - but only when appropriate by the clinical condition of the patient. Avoid stimulating drinks and food, like coffee, tea, nuts and tropical fruits approximately 1-3 days before testing.
