The drug Mandelamine interferes with the test procedure and should be discontinued 48 hours prior to collection of the specimen. This assay is of most value when the specimen is collected during a hypertensive episode.

Specimen:

Aliquot 20 ml (two 10 ml specimens)  from a 24-hour urine collection.  Indicate 24 hour volume.  Before start of collection, add 25 ml 50% acetic acid preservative to the container (15 ml 50% acetic acid for children <5 years old).  Adjust pH to 2.0-4.0 with 50% acetic acid. Refrigerated during collection.

Processing: 

Aliquot 50 ml and indicate the 24-hour volume.  Send to Mayo refrigerated.
Separate aliquots must be submitted for Metanephrines and VMA if collected with this specimen. Identify which specimen is for Catecholamine Fractionation.  Catecholamine Mayo # 9276.
