Erythrocytosis is an increase in the amount of red blood cells in the bloodstream. The condition is also referred to as polycythemia, but polycythemia can also imply an increase in all types of blood cells (including white blood cells and platelets). Erythrocytosis can be relative, transient, or absolute.

Mar 25, 2024 · Polycythemia, erythrocytosis, and high red blood cell count are all used to describe the increase in RBC either in quantity, hemoglobin (protein that carries oxygen), or PCV. This increase in red blood cells causes them to collect on the walls of red blood vessels, also called sludging. This causes vessel damage, clot formation, and poor ...

The patient was an 8-year-old intact male border collie presented to his primary care veterinarian for hematemesis. At the time of examination, mild preputial bleeding was noted. A complete blood count (CBC) revealed a markedly elevated hematocrit of 83%. Eight days later, after additional preputial bleeding was noted, a recheck CBC indicated a per...
At the time of presentation to our referral hospital, no additional bleeding episodes were reported. Physical examination revealed moderate conjunctival hyperemia but was otherwise unremarkable, with no evidence of dehydration. An additional CBC indicated that the spun packed cell volume (PCV) was elevated at 76%; plasma protein was within referenc...
After 500 mL of blood was removed by jugular phlebotomy, 800 mL of lactated Ringer’s solution was administered through a cephalic catheter. The PCV after phlebotomy was 65%. Two weeks later, the patient’s PCV had increased to 75% and another 500 mL of blood was removed from the jugular vein. PCV after the second phlebotomy was 55%. After the target...
Primary erythrocytosis (polycythemia vera) is a myeloproliferative disease resulting from the autonomous clonal expansion of hematopoietic progenitor cells that has been reported in dogs, cats, horses, and ferrets. RBC production is dramatically increased, whereas serum erythropoietin (EPO) activity typically is low or low-normal.
Dogs with transient polycythemia rarely develop any complications and the condition usually reverses itself quickly so treatment may not be required. General supportive therapies for canines in distress could include treatments such as IV fluid therapy to prevent additional dehydration and to improve blood pressure, medications to dilate the bronchial tubes and oxygen supplementation.
Erythrocytosis, regularly used synonymously with polycythemia, is a disease in which the bone marrow produces too many red blood cells. The primary difference between erythrocytosis and polycythemia is that polycythemia may be linked to leukocytosis, thrombocytosis, and erythrocytosis. This disease is rare in dogs.

Hence, polycythemia would be more appropriately called erythrocytosis and clinically refers to an increase to an above normal red blood cell count, hematocrit or packed cell volume (PCV), and hemoglobin (Hb) concentration. Polycythemic animals will not show clinical signs until the PCV reaches >60% with some of the highest PCVs exceeding 85%.
