Benign White Cell Disorders

Welcome to the section on benign white cell disorders. We will begin with a discussion of disorders where there are either too few (leukocytopenia) or too many (leukocytosis) white cells in comparison to the expected normal number.

Remember, the normal adult peripheral WBC count or leukocyte count is 4.5-11.0 x 10 /L.

When the WBCc increases or decreases it is the absolute number of the individual components (the neutrophils, the eosinophils, the basophils, the monocytes, and the lymphocytes) that is critical to discovering the cause of the abnormal WBC count.

In the section we will look at decreases in white cell number or leukopenia.
