In normal adults every 1 mm3 of blood are approximately 6,000 to 9,000 grains of leukocytes. If there is an infection that number could increase to 25,000 per mm3. The state of white blood cells is called leukocytosis more than normal, for example in patients with leukemia white blood cell count can reach 200,000 per mm3 of blood.

We recommend that if the number of white blood cells is less than normal (less than 6,000 per mm3) called leukopeni. In patients with typhoid number of leukocytes can be decreased up to 3,000 eggs per mm3 of blood. Function of white blood cells is to protect the body from infection.
In connection with the function of white blood cells has the properties: can form antibodies, can eliminate the disease by eating seeds (phagocytes); can penetrate the vessel wall and move toward the prey (diapedesis). White blood cells fight germs losers will be pus.
