Schilling's classification and haemogram

Related people

Haemogram. A differential count of the leukocytes, in which the polymorphonuclear neutrophil cells are divided into four categories according to number and arrangement of the nuclei in the cells. The so-called Schilling’s haemogram indicates the different developmental stages and an increase in juvenile forms indicates the presence of acute infection or of immature bone marrow as in leukaemia.
