It is characterized by having a nucleus which is curved, but not lobar.The term band cell implies a granulocytic lineage (e.g. neutrophils).n increase in band neutrophils typically means that the bone marrow has been signaled to release more WBCs and increase production of WBCs, also known as a left shift .
