Imprecision of ratio-derived differential leukocyte counts.
Differential leukocyte counts are very imprecise if determined as the product of a total WBC and a percentage obtained by differentiation of a relatively small number of cells. The imprecision can be decreased by increasing simultaneously the numbers of both the counted and the differentiated cells. An increase of only one (such as by automated counting of the WBC) without a simultaneous increase of the other one does not lead to an appreciable reduction of the imprecision.

The imprecision of the ratio of two percentages observed in differential white blood cell counts: a warning.
Ratios of two percentages observed in differential counts of leukocytes or lymphocytes are very imprecise if they are based on relatively small numbers of cells. This is shown by the length of the 95% confidence intervals for such ratios. A formula is given for computing the limits of such intervals. They should accompany each observed value for a ratio.
