Hematologic profiles of 462 persons, mostly active-duty service members, were studied to determine whether hematologic differences between blacks and whites exist in a healthy population. Whites had significantly greater mean concentrations of leukocytes (6.73 vs 5.95 x 10(9)/L), neutrophils (3.96 vs 3.16 x 10(9)/L), and hemoglobin (153 vs 135 g/L for men, 147 vs 125 g/L for women). The mean differences were largely due to relatively symmetric shifts in the frequency distributions for these cell concentrations. No significant correlation was found between neutrophil count and morbidity from infection as measured by a standardized questionnaire. The use of separate hematologic reference values for blacks and whites should be considered.
对462人（大多数为现役军人）的血液学指标进行了研究，以确定健康人群中黑人和白人之间是否存在血液学差异。白人的白细胞平均浓度（6.73对5.95×10⁹/L）、中性粒细胞（3.96对3.16×10⁹/L）和血红蛋白（男性为153对135 g/L，女性为147对125 g/L）显著更高。平均差异主要是由于这些细胞浓度的频率分布相对对称变化所致。通过标准化问卷测量，未发现中性粒细胞计数与感染发病率之间存在显著相关性。应考虑为黑人和白人使用不同的血液学参考值。
