Azurophilic
a term used to describe the reddish-purple staining characteristics of certain cells or cell structures; having a affinity for azureyes.
Band
Cell - an immature granulocyte with a non segmented nucleus; a “stab cell”
Basophil
A white blood cell containing basophilic-staining granules in the cytoplasm
Basophilic
Blue in color; habing affinity for the basic stain
Eosinophil
A white blood cell containing eosinophilic granules in the cytoplasm
Erythrocyte
Red blood cell; RBC
Leukocyte
White blood cell; WBC
Lymphocyte
A small basophilic-staining white blood cell having a round or oval nucleus and playing a vital role in the immune process
Megakaryocyte
A large bone marrow cell from which platelets are derived
