Leukopenia, Neutropenia, and Reduced Hemoglobin Levels in Healthy American Blacks

摘要: 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 leukocytes (6.73 vs 5.95×10 9 /L), neutrophils (3.96 3.16 × 10 hemoglobin (153 135 g/L for men, 147 125 women). The largely due relatively symmetric shifts the frequency distributions these cell concentrations. No significant correlation was found neutrophil count morbidity from infection as measured by standardized questionnaire. use separate reference values should be considered.
