WBC's | Definition |
Leukocytes | 4,500 to 11,000, WBC's |
Leukocytosis | increase in WBC's, inlammation, infection, stress, over 11,000 |
Leukopenia | decrease in the number of WBC's, bone marrow suppression, viral infection, less then 4,000 |
Neutrophils | 45-75%, WBC with differential |
Neutrocytosis or neutrophilia | elevated, due to inflammation, bacterial infection, stree |
Neutropenia | decreased, due to viral infection, overwhelming bacterial infection, bone marrow suppression |
Bands | immature neutrophils, 0-5% |
Left shift | elevated neutrophils and bands, due to bacterial infection, NOT viral |
Eosinophils | 0-8% |
Eosinophilia | elevated, due to allergic reaction, hay fever, asthma |
Eosinopenia | decreased, due to increase adrenal steroids, steroid therapy |
Basophils | 0-3% |
basophilia | elevation, due to severe hypersensitivity response, over 3% |
Basopenia | decreased, due to corticosteroids |
monocytes | 4-11% |
monocytosis | elevation, due to chronic inflammatory disorders, infection, TB, over 11% |
Monopenia | decreased, due to bone marrow depression, steroids, less then 4% |
Lymphocytes | 16-46% |
Lymphocytosis | viral infection, leukemia acute/ chronic, over 46% |
Lymphopenia | decreased, due to bone marrow depression, less the 16% |
