Quantitative Inductively Coupled Plasma-Mass Spectrometry
New York DOH Approval Status
Royal Blue (EDTA).
Centrifuge whole blood and separate RBCs from plasma within 2 hours of collection. Transfer 2 mL RBCs to an ARUP Trace Element-Free Transport Tube (ARUP supply #43116) available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. (Min: 0.6 mL)
Room temperature. Also acceptable: Refrigerated.
Specimens collected in tubes other than royal blue (EDTA). Specimens transported in containers other than Royal Blue (EDTA) tube or Trace Element-Free Transport Tube. Clotted or grossly hemolyzed specimens.
After separation from plasma: Ambient: 2 weeks; Refrigerated: 2 weeks; Frozen: Unacceptable
Copper concentrations in RBCs reflect the intracellular stores and general homeostasis of Copper. Results may be falsely elevated if RBCs in the submitted specimen are lysed or not promptly separated from plasma.
