Patient discussion about leukocytes

Q. can i get a short explanation about white blood cells and their job? what does it mean if i have a insafition

A. White blood cells (WBC's) are the ones responsible for the immune system in the body. The white blood cell count rises in cases of infection, steroid use and other conditions. A low white blood cell count can have many causes, which need to be further evaluated by a doctor.
