Cobalt | ruminants, B-12 molecule, excess causes polycythemia |
Polycythemia | decrease in RBC |

Polychromasia | variation in the hemoglobin content of erythrocytes. |
Hypochromasia | abnormal decrease in the hemoglobin content of the erythrocytes. Pale color |
Poikilocytosis | presence in the blood of erythrocytes showing abnormal variation in shape; acanthocyte, echinocyte, leptocyte, spherocyte, schistocyte |
acanthocyte | A red blood cell characterized by multiple spiny cytoplasmic projections and found in acanthocytosis dogs and liver disease. |
echinocyte | burr cell, crenated or dehydrated, improper blood smear |
Leptocyte | An abnormally thin or flattened red blood cell having a central rounded pigmented area, a middle pigmentless zone, and a pigmented edge. Target and folded cells |
