Morphology: reactive lymphocytes have a heterogenous appearance with variable size, nuclear shape, and amount and color of cytoplasm. Compared to non-reactive lymphocytes, reactive lymphocytes are usually larger with darker blue cytoplasm,… Read more Reactive Lymphocytes →
Morphology: lymphocytes with pink or red cytoplasmic granules. Granular lymphocytes are either cytotoxic T-cells or natural killer cells. Look alike: granulocytes (eosinophils, basophils) Clinical relevance: present in low numbers in healthy animals… Read more Granular Lymphocytes →
Also called: mature neutrophils, segmented neutrophils (segs), polymorphonuclear cells (PMN) Morphology: granulocyte with an indented (segmented) nucleus and white or pale pink cytoplasm. Canine and bovine neutrophils may contain small pink… Read more Neutrophils →

Morphology: leukocytes with pleomorphic nuclei (usually lobulated but may be round or kidney-shaped) and blue-gray cytoplasm containing occasional vacuoles or fine pink granules. Monocytes are larger than most other leukocytes.… Read more Monocytes →
Morphology: small round leukocytes with round or indented nuclei, dark clumped chromatin, and small amounts of light blue cytoplasm. Cattle have small lymphocytes (as described), as well as large lymphocytes with… Read more Mature Lymphocytes →
