*Signifies statistical significant among the different systems (p < 0.0001).
If two systems share a common superscript letter within a row, then they are not significantly different (p > 0.05). Platelet and total leukocyte concentrations are reported as cells/μL. The median (and range) are reported for the leukocyte subpopulations (neutrophils, band neutrophils, monocytes, lymphocytes, eosinophils, and basophils) in cells/μL × 103.
