Neutrophil - canine
Neutrophil - canine

Neutrophils possess a densely-stained, clumped nucleus that develops more segments as it ages. The cytoplasm is clear to pale blue/grey with many small light pink granules. Also referred to as a polymorphonuclear leukocyte.

Lymphocyte - canine
Lymphocyte - canine

Lymphocytes are most commonly seen in their smaller form in cats, but can also be medium to large in size. It has a high nucleus:cytoplasm ratio. The nucleus is round (free of segments) with coarse chromatin clumping. The cytoplasm is blue and often scant.

Monocyte & Lymphocyte - canine

Lymphocytes are most commonly seen in their smaller form in dogs, but can also be medium to large in size. It has a high N:C ratio. The nucleus is round (free of segments) with coarse chromatin clumping. The cytoplasm is blue and often scant. Monocytes are the largest of all leukocytes. It possesses a pleomorphic nucleus with fine, lacy chromatin that stains lighter than other leukocytes. There is abundant blue-grey cytoplasm which appears "foamy" and often contains vacuoles (bubbles).

Eosinophil - canine
Eosinophil - canine

Eosinophils is similar in size to the neutrophil. The nucleus is often band-shaped or limited to two or three lobes. The chromatin is clumped and stains dark, as in the neutrophil. The cytoplasm is light blue but is often obscured due to the presence of numerous medium-sized eosinophilic granules that stain orange-pink.
