We calculated central-95-interpercentile reference values for serum ferritin (SF).
Serum samples were collected from the Fangchenggang Area Male Health and Examination Survey (FAMHES). After screening, we enrolled a total of 1,223 Chinese Han men between the ages of 20 and 69 years. SF values were measured by electrochemiluminescence immunoassay. The two-sided 95-percentile reference values were calculated using both parametric and nonparametric statistical methods.
SF values were distributed log-normally. The central-95-percentile reference values for SF were 88.2-771.7 μg/L (nonparametric) or 104.0-832.2 μg/L (parametric). Neither the non-smoking and smoking group (P=0.921) nor the non-drinking and drinking group (P=0.584) exhibited any difference in SF. Higher concentrations of SF were associated with a higher Body Mass Index (BMI) (r=0.266, P<10(-5)) but not with increasing age of the participants (P=0.808).
The reference values for SF calculated in this study are higher than previously-reported reference levels.
我们计算了血清铁蛋白（SF）的 95%中心百分位参考值。
从防城港男性健康与体检调查（FAMHES）中采集血清样本。经过筛选，我们共招募了 1223 名年龄在 20 至 69 岁之间的汉族男性。SF 值通过电化学发光免疫分析法测定。使用参数和非参数统计方法计算双侧 95%百分位参考值。
SF 值呈对数正态分布。SF 的 95%中心百分位参考值为 88.2-771.7μg/L（非参数）或 104.0-832.2μg/L（参数）。非吸烟组和吸烟组（P=0.921）以及非饮酒组和饮酒组（P=0.584）之间的 SF 值没有差异。SF 的浓度越高，体重指数（BMI）越高（r=0.266，P<10(-5))，但与参与者的年龄增加无关（P=0.808）。
本研究计算的 SF 参考值高于以前报告的参考水平。
