Data on various species compiled and adapted in part from multiple sources, including Latimer KS, Duncan & Prasse’s Veterinary Laboratory Medicine: Clinical Pathology, 5th ed., Wiley-Blackwell, 2011; and Weiss DJ, Wardrop KJ, Schalm’s Veterinary Hematology, 6th Ed., Wiley-Blackwell, 2010. Reference ranges vary between laboratories. Values provided by the reference laboratory should be used.

MCV = mean corpuscular volume

MCH = mean corpuscular hemoglobin

MCHC = mean corpuscular hemoglobin concentration

MPV = mean platelet volume
