It is not uncommon for urine tests to reveal white blood cells or leukocytes. Usually, they signal nothing more concerning than a urinary tract infection, which is quite easily treated. Doctors can detect leukocytes in urine with routine urine tests.


1. What Are Leukocytes and What Do They Do?

Germs are always trying to enter the body. If they succeed, illness can follow. Fortunately, our immune systems are ready and waiting to fight off germs and keep us healthy. At the front line of defense is an army of leukocytes or white blood cells. When a potentially harmful bacteria or virus breaches the skin barrier, leukocytes spring into action to neutralize the danger. They fend off germs in a variety of ways: some produce antibodies to fight the bug, while others completely engulf the threatening agent.
