GRAN stands for Granulocytes, which is a part of the WBCs. There are 5 types of WBCs (Differential Count): Neutrophils, Lymphocytes, Monocytes, Eosinophils and Basophils. A collective count of Monocytes, Eosinophils and Basophils are together called Granulocytes. In the less advanced cell counters, ie. the 3 Part Differential Cell Counters, Neutrophils, Lymphocytes and Granulocytes are counted whereas in 5 Part Differential Cell counters, Neutrophils, Lymphocytes, Monocytes, Eosinophils and Basophils are counted separately and more accurately.
