Description:
A calculated measurement in which the number of basophil granulocytes is divided by the number of all white blood cells in a specified sample of peripheral venous blood, and the result presented as a ratio, fraction, quotient or percentage. A basophil is a granular leukocyte with an irregularly shaped, relatively pale-staining nucleus that is partially constricted into two lobes, and with cytoplasm containing coarse granules of variable size that stain bluish-black when exposed to basic dyes.
