This assay is of most value when the specimen is collected during a hypertensive episode.  For children 14 years old and younger, Mayo #9254 (VMA and Homovanillic Acid, Pediatric uring) is the recommended test.

A single 24-hour urine collection may be used for CATECHOLAMINE FRACTIONATION, METANEPHRINES [METN24U] and VMA [VMA24UR].    The specimen must be kept refrigerated during collection.

Amoxicillin interferes.  Discontinue for 3 days prior to collection.
The drug Mandelamine interferes with the test procedure and should be discontinued 48 hours prior to collection of the specimen.

 Before start of collection, add 25 ml 50% acetic acid preservative to the container (15 ml 50% acetic acid for children <5 years old).  RL clients, please call Mercy Lab to have a jug prepared with preservative.  Refrigerate during collection.

Separate aliquots must be submitted for Metanephrines and Catecholamines if collected with this specimen.  Identify which specimen is for VMA. Mayo #9454
