Basophils are one of the five types of white blood cells. Although they make up only a small portion of the total white blood cells normally present, basophils play an important part and are responsible for the release of histamines and other chemicals. Often the release of histamines, in response to exposure to mold or dander, will result in some of the symptoms of asthma.
Like eosinophils, basophils are white blood cells that concentrate on dealing with allergic reactions.
Normal results for the percentage of the white blood cells that are basophils are between 0.5% and 1%.
