本文用放免法分别测定27日龄到61岁各年龄组男女性血清铁蛋白正常值。认为以百分位数法(P_(2.5)～P_(97.5))所定血清铁蛋白正常值范围的下限,可作为诊断缺铁性贫血的极限指标。血清铁蛋白含量受发热、炎症、恶性疾患等多种因素的影响,故对合并此类疾病的非单纯性缺铁性贫血病例在鉴别诊断时应予以注意。本测定有助于某些恶性疾病的诊断,但其临床价值还有待于进一步观测。
In this paper, radioimmunoassay was used to determine the normal values of serum ferritin in men and women of all ages from 27 days to 61 years old. It is considered that the lower limit of normal range of serum ferritin determined by the method of percentile (P_ (2.5) ~ P_ (97.5)) can be used as a limit index for diagnosing iron deficiency anemia. Serum ferritin content by fever, inflammation, malignant disease and other factors, so the combination of such diseases in patients with non-simple iron deficiency in the differential diagnosis should be noted. The determination of some helpful to the diagnosis of malignant diseases, but its clinical value remains to be further observed.
