Assessment of Regeneration in Anemia
Parameter | Regenerative Anemia | Nonregenerative Anemia |
|---|---|---|
Absolute reticulocyte count | In dogs: > 60,000 reticulocytes/mcL In cats: > 50,000 aggregate reticulocytes/mcL* | In dogs: < 60,000 reticulocytes/mcL In cats: < 50,000 aggregate reticulocytes/mcL* |
Corrected reticulocyte percentage | > 1% | < 1% |
Mean corpuscular volume | Macrocytosis | Microcytosis to normocytosis |
Mean corpuscular hemoglobin concentration | Hypochromia | Normochromia |
Other characteristics | Polychromasia, nucleated RBCs | Lack of response in 3–5 days |
*For cats (which have both aggregate and puntate reticulocytes), only aggregate reticulocytes are included in a reticulocyte count. | ||
