|Performed by||UC Irvine|
|Method||Inductively Coupled Plasma Mass Spectroscopy (ICPMS)|
|Patient Preparation||The patient should refrain from taking vitamins or mineral supplements for at least 3 days prior to specimen collection.|
|Collection Instructions||Because Zinc levels display a circadian rhythm which peaks at 0900 and 1800, specimens should always be drawn at the same time of day.
Be sure to gently mix the specimen promptly after phlebotomy.
