Depending on the degree of immaturity blasts metamyleocytes promyelocytes would determine what is wrong.

. Less commonly l View the full answer. What does a left arrow mean in medical. A left shift is an increase in the number of immmature neutrophils or polymorphonuclear leukocytes PMNs.

Mostly it refers to the white blood cell lineage particularly neutrophil-precursor band cellsthus signifying bandemia. For example with an acute infection the white blood cell count may increase to 15000 the bands to 10 and the neutrophils to 65.

CBC may reveal leukocytosis with shift to the left during acute exacerbation. Less commonly left shift may also refer to a similar phenomenon in severe anemia when reticulocytes and immature erythrocyte precursors appear in the peripheral circulation.

The most mature cells segmented neutrophils were assigned to the right-most button the least mature cells myeloblasts were assigned to the left-most button and the other stages of cells were spread. Eight key cell counter.

Thus when the number of immature forms present exceeded their normally small or non-existent percentages it was often defined as a shift to the left. The term left shift almost always refers to the neutrophil series. What is shift to the left.
