COMPARISON OF MORPHOLOGICAL AND ETIOLOGICAL CLASSIFICATION OF ANAEMIA
|
Morphological classification
|
Etiological classification
|
Normocytic normochromic
|
- Normal erythrocyte morphology
- Depression of erythrogenesis
- Chronic inflammation
- Chronic renal insufficiency
- Endocrine deficiencies
- Neoplasia
- Marrow hypoplasia as with bracken fern poisoning, radiation, ehrlichiosis, chloramphenicol toxicity, excess estrogens, phenyl butazone
- Acute haemorrhage after fluid volume has been restored and before regeneration occurs
- Feline leukemia virus
|
Normocytic hypochromic
|
- Early (days to week) iron deficiency
|
Macrocytic normochromic (no reticulocytosis)
|
- Vit B12 and folate deficiencies
- Cobalt deficiency in ruminants
- Poodle macrocytosis (healthy miniature poodles, no anaemia)
- Feline leukemia virus- related dyscariasis (no reticulocytosis)
- Regenerative anaemias
|
Macrocytic hypochromic
|
- Markedly responsive anaemias (with reticulocytosis )
- Vit B12 and folate deficiencies
|
Microcytic normochromic
|
- Characteristic of the Japanese Akita breed of dogs
- Iron deficiency in progression
|
Microcytic hypochromic
|
- Iron and copper deficiencies
- Chronic blood loss
- Pyridoxine deficiency
