Our hospital's veterinarians have access to hematology analyzers which perform complete blood counts (CBC). A CBC is a blood test used to measure and evaluate cells that circulate in the blood. The test includes an actual counting of red blood cells, white blood cells and platelets and a blood smear is viewed under the microscope. A CBC is indicated in any ill animal and it is also performed prior to anesthesia or surgery to evaluate general health. A CBC is a useful screening test for underlying infection, anemia and illness in pets.
