This statement is true. The term 'shift to the left' originates from the old practice of recording differential counts from left to right on a paper chart, with immature cells on the left and mature cells on the right. In a severe bacterial infection or inflammatory state, the demand for neutrophils rises sharply. The bone marrow responds by releasing not only mature segmented neutrophils but also their immediate precursors—band neutrophils, metamyelocytes, and sometimes even myelocytes—into the bloodstream. This increase in immature forms is called a 'left shift.' It indicates that the bone marrow is under stress and trying to meet the demand, and it is a classic sign of a bacterial infection or an acute inflammatory process.
