White Blood Cell Differential Test
The White Blood Differential Test measures the percentage (and absolute values) of each type of white blood cell (WBC) that you have in your blood.
Five different types of white blood cells, also called leukocytes, normally appear in the blood:
- Neutrophils
- Lymphocytes
- Monocytes
- Eosinophils
- Basophils
The test shows if the number of cells are in proper proportion with one another, and if there is more or less of one cell type.
What do abnormal results mean?
Any infection or acute stress increases your number of white blood cells. High white blood cell counts may be due to inflammation, an immune response, or blood diseases such as leukemia. It is important to realize that an abnormal increase in one type of white blood cell can cause a decrease in the percentage of other types of white blood cells.
Although your white blood cells account for only about 1 percent of your blood, their impact is significant. White blood cells are essential for good health and protection against illness and disease. Think of white blood cells as your immunity cells. In a sense, they are continually at war. They flow through your bloodstream to battle viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness. White blood cells are produced inside the bone marrow and stored in your blood and lymphatic tissues. Because some white blood cells have a short lifespan of one to three days, your bone marrow is constantly producing them.
