1

Consists of RBC count, indices, and differential, WBC count, PCV, TP, HgB, Platelet estimate, and retic count

Complete Blood Count (CBC)

2

A high WBC count is called

leukocytosis

3

Low WBC count is called

leukopenia

4

3 Phagocytic WBCs

Monocytes, Eosinophils, and Neutrophils
MEN LIKE TO EAT

5

3 granulocytes

Basophils, Eosinophils, and Neutrophils
BEN HAS A GRAINY SENSE OF HUMOR

6

Glass slide used to do a manual WBC count

Hemacytometer

7

WBC maturation process

1. Myeloblast
2. Promyelocyte
3. Myelocyte
4. Metamyelocyte
5. Band cells
6. Neutrophils

8

Youngest form of WBC with large, round cell
Prominent nucleolus

Myeloblast

9

Has a perinuclear, clear zone (white)

Promyelocyte

10

May contain a single indentation

Myelocyte

11

Kidney shaped nucleus
Chromatin is granular and condensed

Metamyelocyte

12

Horse-shoe shaped nucleus

Band neutrophils

13

Multiple segments
Chromatin is very condensed

Segmented Neutrophils

14

5 or more segments is

hypersegmented

15

These have large, rod shaped granules
Look like red raspberries

Eosinophils

16

Normal WBC in dogs

6.0-17.0 x 10^3/mm3

17

Normal WBC in cats

5.5-19.5 x 10^3/mm3

18

First line of defense of the leukocytes
Produces pyrogen that leads to inflammation and fever

Neutrophils

19

A lot of band cells
Presence of non-segmented neutrophils caused by inflammation

Left Shift

20

Neutrophils in avian patients

Heterophils

21

Bigger in size with a frothy cytoplasm
Have vacuoles with blue tint to cytoplasm

Toxic cells

22

Abundance of hypersegmented neutrophils
An increase in the number of mature neutrophils but no immature cells are present

Right Shift

23

Decrease in neutrophils

Neutropenia

24

Seen with allergic reactions
Deactivates histamines and release lysosomes to kill/damage parasites

Eosinophils

25

Causes acute allergic reactions by releasing histamines
Carry heparin to keep blood from clotting

Basophils

26

T Cells and B Cells
Agranular and mononuclear

Lymphocytes

27

These lymphocytes appear after an animal is vaccinated

Reactive

28

Highly phagocytic
Larger than other WBCs

Monocytes

29

When monocytes travel to tissues they are called

Macrophages

30
