Differential white blood cell count, also known as a leukocyte count, is a crucial test to determine the different types of white blood cells present in the blood. The cells are classified into granulocytes (neutrophils, eosinophils, basophils) and agranulocytes (lymphocytes, monocytes). Blood smear
