Specimen
Packed RBCs and plasma
Volume
3 mL each plasma and packed RBCs
Container
Royal blue-top (EDTA) metal-free tube; metal-free transfer tubes
Collection
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.
