- Place Infections: An elevated count much points to an combat-ready bacterial or viral infection.
- Supervise Inflammation: Continuing inflammatory conditions often cause displacement in white blood cell levels.
- Tax Immune System Function: Patient with compromise immune systems demand regular monitoring to insure their body can protect itself.

|---|---|---|
| Leukocytosis | Eminent WBC count | Infection, focus, rubor, or bone marrow disease. |
| Leukopenia | Low WBC numeration | Autoimmune upset, chemotherapy, or vitamin lack. |
