CADMIUM, URINE
Reporting Title: Cadmium, U
Methodology: Inductively Coupled Plasma-Mass Spectrometry (ICP-MS)
	Test Performed At:
		Mayo Medical Laboratories #8678
	Specimen Required:
		Submit an entire 24-hour urine collection in a urine container (with no metal cap(s) or glued inserts) supplied by St. Louis Children’s Hospital. Refrigerate specimen during collection, and send specimen refrigerated. Call 314-454-4161 to obtain container. Please note collection start & stop times and dates on container.
		CAUTION:			Collection of urine specimens through a catheter frequently results in elevated values, because rubber contains trace amounts of cadmium that are extracted as urine passes through the catheter.
		NOTES:			1.	High concentrations of gadolinium and iodide are known to interfere with most metals tests. If either gadolinium- or iodide- containing contrast media has been administered, a specimen cannot be collected for 48 hours.
					2.	Random urines will also be accepted for testing in which a minimum of 2.0 mL of urine should be sent. Make sure order is for Cadium, Random Urine.
	Laboratory Notes:
		1.	Send 10 mL (minimum: 2.0 mL) from a 24-hour urine collection, collect in clean, plastic urine container(s) with no metal cap(s) or glued insert(s). No preservative. See special instructions “Urine Preservatives” for multiple collections.
		2.	Send specimen in a plastic, 13-mL urine tube or in a clean, plastic aliquot container with no metal cap or glued insert. See special instructions “Metals Analysis — Collection and Transport” for complete instructions.
		3.	Refrigerate specimen within 4 hours of completion of 24-hour collection. Send specimen refrigerated.
		NOTE:		24-HOUR VOLUME IS REQUIRED ON REQUEST FORM FOR PROCESSING.
	Urine Preservative Collection Options
