Band neutrophil

Band neutrophils comprise approximately 1 to 3% of the peripheral leukocytes. They are usually 9 to 15 µm in diameter. The nucleus forms a "U" or curled rod prior to segmentation. The chromatin pattern is coarse and clumped. The cytoplasm is moderate to abundant with a few nonspecific granules and many specific granules.
