Patient: My 4 yr old old has just had a blood test return with a low white cell count, he also has unusual bruising on his kidneys, legs and arms. Complains of leg pain frequently and stomache aches as well
Doctor: White blood cells are responsible for immunity and defending the body against infectious organisms or foreign bodies. Th e normal range of total white blood cells is 4.4 – 11 * 109/L, however laboratories vary slightly in their reference ranges. Leucopenia or low white blood cell count could be caused by a number of factors. A recent flu/cold, certain medications and certain disease cause a low white cell count. A decreased white blood cell count could mean that your child’s body defence mechanisms are not functioning properly increasing the risk of infections. I would recommend consulting your child’s pediatrician for further work-up. Considering your child’s symptoms, Juvenile Rheumatoid arthritis and Felty’s syndrome need to be ruled out.
