Leukocyte Count of 500/µL: Is It Normal?
A leukocyte (white blood cell) count of 500/µL is severely low (normal adult range: 4,500–11,000/µL). This indicates leukopenia and requires urgent medical evaluation for causes such as:
- Bone marrow suppression (chemotherapy, radiation, medications)
- Severe infection (sepsis)
- Autoimmune disorders
- Nutritional deficiencies (B12, folate)
- Hematologic malignancies
Action
Contact a healthcare provider immediately. Do not assume this is normal.
