What Do White Blood Cells Do?

10. White Blood Cell Count
Although white blood cells make up only a small proportion of all blood cells, it is still important that they exist in the right balances. If there were too many, or too few, then the patient can encounter a number of unwelcome problems.
Too many white blood cells will not necessarily cause symptoms, but it can cause symptoms including but not limited to fever, bruising, fainting, and bleeding. If there are too few white blood cells, however, then the patient is going to be more susceptible to disease as their immune system is weakened. An abnormal blood cell count either way can be a sign of a potentially serious underlying cause.
