Definition of Pediatric white blood cell disorders
Your body produces white blood cells (leukocytes), which help fight bacterial infections, viruses and fungi. There are several types of white blood cells, each with a different disease-fighting activity.
A white blood cell disorder can mean that your child has too few or too many white blood cells of a certain type, which can cause, or be caused by, serious health problems. Types of white blood cell disorders include low white blood cell count (leukopenia), high white blood cell count (leukocytosis), neutropenia, lymphocytopenia, monocyte disorders and eosinophilia, among others.
