what causes elevated retic count
So anemia from any cause should cause an increase in your petâs reticulocyte count. Rather than list all of those causes again, find them listed for the reason your petâ PCV or hemoglobin might be low. In kittens and puppies, heavy flea infestations are a common cause. Intravascular (within the blood vessels) red blood cell destruction (hemolysis) can also increase your pet's reticulocyte count.
Occasionally, both the reticulocyte count and the RBC count will be increased because of excess RBC production by the bone marrow. This may be due to an increased production of erythropoietin, disorders that cause chronic overproduction of RBCs (polycythemia vera), and cigarette smoking.
