Your white blood cell (WBC) count reflects your body’s immune response. A normal range typically falls between 4,500 and 11,000 cells per microliter of blood. However, this can vary slightly depending on the laboratory and the individual’s age and health.
Understanding WBC Subtypes
WBCs aren’t all the same; they have different roles in fighting infection and disease. Five main types exist: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each type’s percentage within your total WBC count provides a more detailed picture of your immune health. A complete blood count (CBC) with differential will show these percentages.
Normal Ranges for WBC Subtypes
| Neutrophils | 40-70% |
| Lymphocytes | 20-45% |
| Monocytes | 2-8% |
| Eosinophils | 1-6% |
| Basophils | 0.5-1% |
Deviations from these ranges can indicate various conditions. For example, high neutrophil counts often suggest bacterial infection, while elevated lymphocytes might point toward a viral infection. High eosinophil counts can be associated with allergies or parasitic infections. Monocyte elevations can sometimes signify chronic inflammation. It’s crucial to discuss any abnormal results with your doctor for proper interpretation and diagnosis.
Important Note: Individual Variation
Keep in mind that normal ranges are guidelines. Factors like stress, exercise, and even the time of day can slightly affect your WBC count. A single slightly elevated or low count doesn’t necessarily signal a problem. Your doctor considers your complete medical history and other test results when evaluating your WBC count.
