WBC Count and Differential Flashcards
Consists of RBC count, indices, and differential, WBC count, PCV, TP, HgB, Platelet estimate, and retic count
Complete Blood Count (CBC)
A high WBC count is called
leukocytosis
Low WBC count is called
leukopenia
3 Phagocytic WBCs
Monocytes, Eosinophils, and Neutrophils
MEN LIKE TO EAT
3 granulocytes
Basophils, Eosinophils, and Neutrophils

WBC maturation process
- Myeloblast
- Promyelocyte
- Myelocyte
- Metamyelocyte
- Band cells
- Neutrophils
Youngest form of WBC with large, round cell
Prominent nucleolus
Myeloblast
Has a perinuclear, clear zone (white)
Promyelocyte
May contain a single indentation
Myelocyte
Kidney shaped nucleus
Chromatin is granular and condensed
Metamyelocyte
Horse-shoe shaped nucleus
Band neutrophils
Multiple segments
Chromatin is very condensed
Segmented Neutrophils
5 or more segments is
hypersegmented
These have large, rod shaped granules
Look like red raspberries
Eosinophils
Normal WBC in dogs
6.0-17.0 x 10^3/mm3
Normal WBC in cats
5.5-19.5 x 10^3/mm3
First line of defense of the leukocytes
Produces pyrogen that leads to inflammation and fever
Neutrophils
A lot of band cells
Presence of non-segmented neutrophils caused by inflammation
Left Shift
Neutrophils in avian patients
Heterophils
Bigger in size with a frothy cytoplasm
Have vacuoles with blue tint to cytoplasm
Toxic cells
Abundance of hypersegmented neutrophils
An increase in the number of mature neutrophils but no immature cells are present
Right Shift
Decrease in neutrophils
Neutropenia
Seen with allergic reactions
Deactivates histamines and release lysosomes to kill/damage parasites
Eosinophils
