D72: Other disorders of white blood cells
D72.9: Disorder of white blood cells, unspecified
Blood is made up of a liquid part and different blood cells, among other things. The blood cells include the red blood cells, the white blood cells and the platelets. White blood cells are part of the body’s immune system. They fight pathogens.
The white blood cells may look changed. However, you may have too many or too few white blood cells in the blood. That can have various causes.
The white blood cells may work normally. However, the body may also no longer be able to fight off some of the pathogens properly, causing you to get sick more quickly, for example.
