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.
如果基于相对少量的细胞来观察白细胞或淋巴细胞分类计数中的两个百分比的比值，那么这些比值是非常不精确的。这可由这些比值的95%置信区间的长度来表明。文中给出了计算此类区间界限的公式。这些界限应与每个观察到的比值一同列出。
