Title: Eosinophilic, neutrophilic and basophilic granulocytes in peripheral blood smear (human)
Description: Stain: May-Grünwald-Giemsa (MGG).
The eosinophil (1) is slightly larger than the neutrophil with a diameter of 12-17 µm. The nucleus is usually bilobed (occasionally trilobed).
Eosinophil granules are considerably larger than those of neutrophils, and are stained reddish-orange.
These cells are very fragile and are often damaged during the spreading of blood films. The basophilic granulocyte (2) with a diameter of 10-14 µm has also nuclear lobes which, however, are usually folded over each other and therefore are hardly visible as lobes. The black-purple granules are large and aggregated and tend to cover the nucleus.
The neutrophilic granulocyte (3) has a segmented nucleus with three tot five lobes. The granules are very fine dust-like pale azurophilic.
