Causes of insufficient erythrocytes and leukocytes in the blood?

The number of blood cells depends on the age, sex and health of the person. Red blood cells become smaller with the development of anemia.

A decrease in white blood cell count is associated with certain infections, drugs, or toxic substances that inhibit the formation of new white blood cells.
