The average white blood cell count or leukocyte count is 4,500 to 10,000 per microliter, according to Healthline, although infants have higher ranges. The normal range, differ between individuals, says About Health. Those with their spleens removed often have higher counts, says MedlinePlus.
WBC count is done as part of CBC, or complete blood cell count, according to About Health. Leukopenia and leukocytosis are terms used to describe low and high WBC counts respectively. These counts are associated with several conditions or disorders and do not indicate specific diseases. They are, however, a piece of medical information that doctors can use to assess and monitor the progression of a medical condition or disease.
