Test Details


Evaluate manganese stores


Inductively coupled plasma/mass spectrometry (ICP/MS)

Reference Interval

Plasma: <2.0 ng/mL; RBC: 11.0−23.0 ng/mL

Specimen Requirements


Packed RBCs and plasma


3 mL each plasma and packed RBCs


Royal blue-top (EDTA) metal-free tube; metal-free transfer tubes


Both packed cells and plasma are required. Separate before shipping. Failure to separate may cause rejection due to hemolysis of red cells and contamination of the plasma. Transfer RBCs and plasma into separate plastic, acid-washed, trace metal-free tubes. Specimen must be received at the testing facility within five days of collection.
