Inductively coupled plasma-triple quadrupole mass spectrometry (ICP-TripleQ MS)
Result Included
Zinc
Specimen
Specimen Type
Avoid gel separator tubesPlasma (K2-EDTA)
Containers
Preferred Containers
BD 6 ml K2-EDTA Royal Blue Vacutainer (Reference # 368381)
Volume

2 mL
Specimen Comment
Avoid gel separator tubes.
Collection & Handling
Collection Instructions
Collect in contaminant-free tube. Avoid hemolysis.
Handling Information
Separate as soon as possible and transfer plasma to polypropylene vial. Store and send cold.
Additional Information
Concentrations of zinc are much higher in erythrocytes than in plasma. The results in plasma may be falsely elevated if not separated within 30 m and/or hemolysis is present. Serum concentrations are higher due to release from platelets during coagulation.
