Note on Draw Volumes

The amount of blood to draw for serum or plasma based testing is approximately two times the minimum volume of serum or plasma listed in the procedure catalog.  For example, if the minimum volume is 1mL of serum, draw at least 2mL of blood.  For patients with high hematocrits (i.e. newborns) the draw volume should be approximately three times the minimum volume.
