A basophil is a type of cell belonging to the white blood cell family. While only comprising a small percentage of the total white blood cells circulating in the blood (normal range: 0.4%-1%), they are the largest type of mature white blood cell. They are created in response to inflammation and infection like all white blood cells; however, they are unique in their ability for phagocytosis—the process of immune cells “eating” other cells such as bacteria. Basophils also produce histamine and serotonin, which can induce inflammation in response to an allergen. Finally, basophils also excrete heparin that is used to prevent blood from clotting too quickly. The test used to measure basophil concentration in the blood is called a “blood differential test,” and it measures all five types of white blood cells found in our bodies. The analysis of a blood differential test will also point out abnormal or immature cells.
