White blood cells are responsible for protecting your body against infections and invading organisms. They are 5 types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. A white blood cell (WBC) count measures the number of white blood cells in your blood. A WBC differential determines the percentage of each type of white blood cell that you have in your blood. A WBC differential also reveals if there are any abnormal or immature cells. These two tests are important to help doctors determine if there is any infection or acute stress, and/or blood diseases. The "White Blood Cell Count and Differential Reference" helps you memorize the normal reference ranges of each type of white blood cell for your tests or your work.
