本文报道用~(125)I放射免疫检测广州市两所全日制托幼儿园390名7岁以内小儿的血清铁蛋白(SF)。均值为30.00±12.80ng/ml(按每岁为一年龄组),随年龄的增长,SF值越升高,SF在16ng/ml左右的,为储备铁缺乏(隐性缺铁阶段)但无明显临床症状。提示SF含量的变化对诊断隐性缺铁极为敏感。经铁强化糖浆饮料治疗后,其SF较治疗前明显升高(统计学处理极显著差异),故讲明SF的测定不仅作为缺铁和缺铁性贫血诊断指标,而且还可作为铁剂治疗的疗效指标。
This paper reports the detection of serum ferritin (SF) in 390 children under 7 years of age in two day nurseries in Guangzhou with ~ (125) I radioimmunoassay. Mean age was 30.00 ± 12.80 ng / ml (according to the age of one year group), the SF value increased with age, and the SF was about 16 ng / ml, which was a deficit of reserve iron (recessive iron deficiency stage) but no Obvious clinical symptoms. Tip SF changes in the diagnosis of iron deficiency is extremely sensitive to iron deficiency. SF treatment of iron-fortified syrup, the SF was significantly higher than before treatment (statistically significant difference), indicating that the determination of SF not only as a diagnostic indicator of iron deficiency and iron deficiency anemia, but also as a treatment for iron The efficacy index.
