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: poikilocyte is a generic term to describe red blood cells with abnormal shape. Poikilocytosis refers to large numbers of abnormally shaped red blood cells. Commonly seen with: poikilocytosis may include… Read more Poikilocytosis →
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 →
Metarubricyte: most mature form of nucleated red blood cell (nRBC). Nuclei are small and pyknotic, often eccentric, with condensed (smooth dark) chromatin. Cytoplasm is smooth and uniform and may stain… Read more Nucleated Red Blood Cells →
Morphology: relatively large, uniform red blood cells with central pallor. Lifespan: 110 – 120 days Other features: small numbers of polychromatophils, nucleated red blood cells, and Howell-Jolly bodies may be present… Read more Normal Canine Erythrocytes →
Morphology: red blood cells that stain pain with increased central pallor and thin rim of hemoglobin (decreased hemoglobin content). Look alike: torocytes (increased central pallor with normal thick rim of hemoglobin). Commonly… Read more Hypochromasia →
