a method of determining what percentages of neutrophils in a population have each number of nuclear lobes or segments between one and five; normally over 75 per cent should have two or three lobes. An increase in the percentages with fewer lobes, called a shift to the left, is seen in bacterial infections, whereas an increased number with hypersegmentation of the nuclei, called a shift to the right, is seen in cobalamin and folate deficiency. Called also neutrophil lobe c.
