GRANULOCYTES: Neutrophils, Eosinophils & Basophils; NEUTROPHILS: Polymorphonuclear neutrophil; Polymorphs. EOSINOPHILS: Bilobed nucleus, granules stained by eosinophil/acidic dyes. BASOPHILS: Bilobed nucleus, granules stained blue/basic/basophilic dyes. AGRANULOCYTES: Monocytes & Macrophages. MONOCYTES; granules are non-specific; kidney shaped nuclei. LYMPHOCYTES; very large nucleus, very little cytoplasm. TOTAL LEUKOCYTE COUNT (TLC): Total no white cells in cubic mm of blood, 4000-11000/mm3. Leukopenia, Leukocytosis defined. DIFFERENTIAL LEUKOCYTE COUNT (DLC); Neutrophils: 40%-75%; Neutropenia & Neutrophilia; acute inflammation; Pyogenic infection. Eosinophils: 1%-6%; Eosinophilia; Parasitic infections & Allergic conditions. Basophils: 0%-2%; Basophilia; Type 1 HS reactions. Monocytes: 2%-10%; Monocytosis; Chronic infections; Tuberculous infections. LYMPHOCYTES: 15-40%; Lymphocytosis; classically seen in viral infections & chronic infections.
