Specimen type:
Platelet-free plasma AND serum.
Preferred collection container:
Alternate Collection Container:
4.5 mL blue top (3.2% sodium citrate) tube
Specimen required:
Three (3) 1 mL aliquots of platelet-free citrated plasma , (1) 1 mL aliquot of serum, one (1) 1 mL aliquot of EDTA plasma and one (1) lavender-top EDTA whole blood.
