对100例飞行人员耳垂血与手指血常规检验七项指标进行了对比观察。七项指标为:白细胞(WBC)、红细胞(RBC)、血色素(HGB)、红细胞压积(HCT)、红细胞平均体积(MCV)、红细胞平均血红蛋白量(MCH)和红细胞平均血红蛋白浓度(MCHC)。结果表明WBC、RBC、HGB和HCT四项指标耳垂血检测均值高于手指血,两者有非常显著性差异(P<0.01)。手指血比耳垂血更接近法定正常参考值。建议在飞行人员体检或招飞体检中使用手指血检测血细胞常规项目。
Seven hundred indicators of blood test of ear lobe and finger of 100 pilots were compared. The seven indexes were WBC, HBC, HCT, MCV, MCH and MCHC. The results showed that WBC, RBC, HGB and HCT four indicators of earlobe blood test mean higher than finger blood, both have very significant difference (P <0.01). Finger blood is closer to statutory normal reference than earlobe blood. It is recommended to use finger blood to test routine blood cell items during the pilot’s physical examination or flight test.
