In older dogs and cats, chronic kidney disease is a common cause of anemia. Rupture of a major blood vessel, toxic bone marrow suppression, atypical responses to antibiotics and other medicines and bone marrow tumors can also be responsible for a low hematocrit. Babesiosis, ehrlichia and anaplasmosisin dogs can be responsible for a low hematocrit.Īutoimmune anemias, where red blood cells are destroyed by antibodies generated by the pet’s own body is another fairly common cause of anemia in dogs. īlood parasites (such as haemobartonella/mycoplasmosis in cats. Other than blood loss through the intestines blood loss from wounds to the body or within the body after trauma is another common cause of a low PCV. Blood sucking parasites such as hookworms in dogs or in cats. Here are some of the more common ones: Hemorrhage, including, hemorrhage into the intestinal tract (such as due to parvovirus infection in dogs or coccidiosis infection in kittens). There are too many causes of anemia for me to mention. Reasons Why Your Pet Might Have A Low Hematocrit: The only exception is when the fewer-than-normal red blood cells are larger than normal (a macrocytic anemia or MCV ).
Low hematocrits almost always lead to low hemoglobin levels. The next test, blood hemoglobin content, measures the actual amount of the blood carrying element, hemoglobin, in your pet’s blood. If the red lower portion is anything less than about 40% of the total, your pet is anemic. Normally, about half of the tube then consists of the pet’s straw-colored blood serum at the top, with packed red blood cells at the bottom and a thin layer of white blood cells just above them (the buffy coat). When your dog or cat’s blood is drawn up into a thin glass tube and then spun in a centrifuge, the height of the column of red cells that have spun to the bottom of the capillary tube is its hematocrit.
