For establishment correlation between erythrocyte indices and serum ferritin (SF), to identify infants at eighth months of age, with iron normal corporal stores, were studied 112 infants; 40 cases had severe deficient iron stores (SF < 12 ng/mL), 17 cases with "moderate" deficient iron stores (SF 12-20 ng/mL) and 55 infants with normal iron stores. The mean corpuscular hemoglobin (MCH) was altered in the 40.1%, the mean corpuscular volume (MCV) 29.5% and hemoglobin (Hb) 6.2%. In severe deficient iron stores, the MCH, with abnormal values had minor specificity (0.62), that MCV (0.88). With a SF < 20 ng/mL, specificity of the MCV was 0.92. Simultaneous alteration on MCH and MCV had similar specificity (0.92) and predictive positive values. With abnormal values of CMH + MCV or MCV alone, were established high probability for identify infants with normal iron stores.
为了建立红细胞指数与血清铁蛋白（SF）之间的相关性，对112名8个月大、体内铁储备正常的婴儿进行了研究；40例铁储备严重不足（SF<12 ng/mL），17例铁储备“中度”不足（SF 12 - 20 ng/mL），55例铁储备正常。40.1%的平均红细胞血红蛋白（MCH）、29.5%的平均红细胞体积（MCV）和6.2%的血红蛋白（Hb）发生改变。在铁储备严重不足时，MCH异常值的特异性较低（0.62），MCV的特异性为（0.88）。当SF<20 ng/mL时，MCV的特异性为0.92。MCH和MCV同时改变具有相似的特异性（0.92）和预测阳性值。CMH + MCV或单独MCV异常时，识别铁储备正常婴儿的概率较高。
