The normal range for white blood cells (WBCs) is between 4,000 and 11,000 cells per microliter of blood.
Understanding White Blood Cell Counts
White blood cells are crucial components of the immune system, defending the body against infection and disease. A white blood cell count measures the number of these cells in your blood, and deviations from the normal range can indicate various health conditions.
Normal White Blood Cell Range
Measurement | Range |
---|---|
White Blood Cell Count | 4,000 - 11,000 cells/µL |
-
Low WBC Count (Leukopenia): A count below 4,000 cells/µL might indicate:
- Bone marrow disorders
- Autoimmune disorders
- Severe infections
- Medications
-
High WBC Count (Leukocytosis): A count above 11,000 cells/µL might indicate:
- Infection
- Inflammation
- Allergic reaction
- Certain cancers
- Medications
Factors Affecting WBC Count
Several factors can influence a person's white blood cell count, including:
- Age
- Overall health
- Medications
- Stress
- Infections
When to Consult a Doctor
It's important to consult a doctor if your white blood cell count is outside the normal range. A healthcare professional can evaluate your overall health and determine the underlying cause of the abnormal count. They may order further tests to diagnose the specific condition and recommend appropriate treatment.
