This cell is a metamyelocyte, sometimes referred to as a juvenile. The nuciei of metamyelocytes are indented and kidney-shaped. The N:C ratio is 1:1. The nuclear chromatin stains darker than in myelocytes. The cytoplasm is pink. At times, promyelocytes are mistaken for metamyelocytes because of the shape of the nucleus, but promyelocytes can have indented and irregular nuclei. The final identification depends upon the nuclear chromatin.
