Doctors try to determine if a low red blood cell count is caused by increased blood loss of red blood cells or from decreased production of them in the bone marrow. Knowing whether the number of white blood cells and/or platelets has changed also helps determine the cause of anemia.
White blood cells (WBC) are the soldiers of your kitty's immune system, so a low count means the army is low on manpower. These squiggly leukocytes fight infections head-on and sometimes there are casualties. The reason for a low WBC count can be revealed by a blood screening. General Infection While white blood cell count is often discussed in the context of serious illnesses like cancer or immune-deficiency disorders, a low count doesn't always indicate a fatal disease. In fact, pretty much any infection or inflammation causes a drop in WBC count. The cells are attracted to damaged tissue and pathogens.
