High Basophils count

High Basophils count is also known as Basophilia or Basophilic Leukocytosis. High Basophils count is defined as the Basophil count that is greater than 50 to 100 cells/µL of blood.  The case is detected when the Basophil count exceeds 2% of the differential white cells count.

The normal white blood cell count is very low and it range between 100 cells/µL in infants to 40 cells/µL in adults. Since the normal white blood cell count of Basophil is very low, recognizing the alternations on the normal Basophils count based on the absolute number of cells would be very  difficult. And this is why differential white blood cells count method is more effective in observing alternations on the Basophil count.

Beside the causes of Lukocytosis, High Basophils count can occur as a result of some skin diseases, myeloproliferative disorders, chronic granulocytic leukemia, and ulcerative colitis in occasional cases.
