Polycythemia, also called erythrocytosis, refers to an
increase in the number or concentration of circulating red blood cells (
RBCs).
However, when your veterinarian finds more than a very few red blood cells (
RBCs), the presence of more than a few white blood cells (WBCs),
increased debris and cells that have sloughed from the tubes and ducts that convey urine (casts)- then careful consideration is needed see if they might fit into the reasons you brought your pet to the veterinarian in the first place.
