39 GRANULOCYTES
Granulocytes include neutrophils (bands and segs), eosinophils,
and basophils. In evaluating numerical aberrations of these
cells (and of any other leukocytes), one should first determine
the absolute count by multiplying the per cent value by the
total WBC count. For instance, 2% basophils in a WBC of 6,000/uL
gives 120 basophils, which is normal. However, 2% basophils in a
WBC of 75,000/uL gives 1500 basophils/uL, which is grossly
abnormal and establishes the diagnosis of chronic myelogenous
leukemia over that of leukemoid reaction with fairly good
accuracy.
