Morphology: red blood cells often show artifactual crenation (sharp-pointed margins) with little to no central pallor and mild to moderate poikilocytosis. Lifespan: 70 – 98 days Other features: rouleaux is common. Young… Read more Normal Porcine Erythrocytes →
Morphology: relatively small, uniform red blood cells with little to no central pallor. Lifespan: 140 – 150 days Other features: rouleaux may be prominent in healthy horses. Polychromatophils are not observed in blood… Read more Normal Equine Erythrocytes →
Morphology: relatively small red blood cells with some variability in size and shape and little to no central pallor. Lifespan: 65 – 76 days Other features: rouleaux, occasional Howell-Jolly bodies, and… Read more Normal Feline Erythrocytes →
Morphology: granulocyte with a large irregularly lobulated nucleus, lavender-staining cytoplasm, and numerous purple (basophilic) cytoplasmic granules. Considerable species variation in appearance of basophils. Look alike: mast cells, other granulocytes (neutrophils, eosinophils) Clinical relevance: basophils are… Read more Basophils →
Morphology: stacks of red blood cells (like a stack of coins). Look alike: agglutination. Rouleaux can be distinguished from agglutination with a saline dilution test: place one drop of blood on a… Read more Rouleaux →
