【摘要】 本研究在建立了应用血红蛋白（Hb）、红细胞比积（PCV）、平均红细胞血红蛋白浓度（MCHC）三项简易指标综合判定（简称筛查法）诊断群体儿童营养性贫血性质方法的基础上.现将筛查法诊断202名贫血儿童的结果与测定红细胞游离原卟啉（FEP）和血清中的铁蛋白（SF）、叶酸（FA）、维生素B₁₂(VB₁₂)的“经典法”诊断结果相对比,其阳性符合率:缺铁性贫血为90.8%,大细胞性贫血为87.0%、混合性贫血为84.0%.可以认为筛查法具有准确度高、测定指标少、不需昂贵设备、技术简便和易于掌握等优点,适合在基层特别是对群体儿童贫血调查和防治工作中的应用。更多还原

【Abstract】 In this paper, we set up a screening method to diagnose the types and the causes of nutritional anemia in collective children, according to three simple targets: Hemoglobin （Hb）. Packed Cell Volume （PCV）and Mean Corpuscular Hemoglobin Concentration（MCHC）.Using the screening method,we found that there are 131 children with nutritional iron deficiency anmeia,46 children with nutritional macrocytic anemia and 25 children with nutritional mixed anemia in 202 children. The results were highly in accordance with those by the classical method in which FEP,SF,FA and VB₁₂ must be tested. Their corresponding r（?）tes are 90. 8% for iron deficiency anemia,87. 0% for macrocytic anemia and 84. 0% for mixed anemia. According to the results above, we concluded that the screening method is not only accurate,but also simpler and lower cost,compared with the classical methed.更多还原
