White cells

My GP told me recently that there were white cells in my urine. What is this and is it dangerous?

The white cells that your doctor referred to are the same white cells that are present in the blood. They are an important component of the body’s defence system and can be thought of as a type of scavenger cell that helps to eliminate bacteria from the body. Their presence in the urine suggests that you may have had a urinary infection at that time.
