About Eosinophilic Disorders

Information for Patients

Eosinophil schematic.
In this blood smear, an eosinophil is seen in the lower left of the larger photo, and a nongranulated white blood cell (lymphocyte) is seen at approximately 1 o'clock in the upper part of the field. The remainder of the cells are red blood cells. The eosinophil nucleus stains blue, and has 2 lobes (i.e., the nucleus is bilobed) in contrast to the lymphocyte. Granules in the cytoplasm of the eosinophil are readily apparent, and arrows point to individual granules in the inset.
