Overview
White Blood Cells
Normal Value Range
Pathophysiology
Special considerations
Abnormal values (high)
Abnormal values (low)
Nursing Points General
Normal value range
WBC
4500-10000/mcL
Differential
Neutrophils
40-60%
Bands
3-5%
>8% indicates signal to WBC for more production
Infection or inflammation is severe
Eosinophils
1-4%
Basophils
0.5-1%
Lymphocytes
20-40%
Monocytes
2-8%
Pathophysiology
WBC
Formed in the bone marrow
Responsible for responding to foreign invaders
Creating antibodies (immunity)
Phagocytosis (eating bacteria or fungi)
Multiple types with different purposes
Neutrophils –
inflammation and first response to invader
Eosinophils –
Inflammation
Allergic response
Parasites
Basophils
Inflammation
Allergic response
Lymphocytes
Create antibodies
Recognize antigens
Destroy cells
T Cells
B Cells
Natural Killer cells
Monocytes
Macrophages
Engulf and destroy invaders
Indicative of infection
