Fine light-purple granules, nucleus single to five lobes (highly variable), immature neutrophils, called bands, have a single C-shaped nucleus, mature neutrophils, called segs, have a lobed nucleus, and are often called polymorphonuclear leukocytes when older
Neutrophils characteristics
Coarse reddish granules and a nucleus usually bilobed
Eosinophils characteristics
Coarse deep blue to almost black granules and nucleus often almost hidden by granules
Basophils characteristics
Slightly larger than red blood cells, thin rim of nearly clear cytoplasm, nearly round nucleus appears to fill most of cell in smaller lymphocytes, and larger lymphocytees hard to distinguish from monocytes
Lymphocytes characteristics
Largest WBC; 2-3x larger than RBCs, cytoplasm nearly clear, and nucleus round, kidney-shaped, oval, or lobed
Monocytes characteristics
Cell fragments and single to small clusters
Platelets characteristics
