摘要
目的分析化学发光法与免疫透射比浊法测定血清纤维连接蛋白(FN)的偏倚,为临床实验室选择项目提供一定的依据。方法根据美国临床实验室标准化研究所(CLSI)EP9-A2文件提供的实验流程,每天随机选取临床标本8份,分别用两种方法进行检测,共测定6d,记录实验结果。结果以免疫透射比浊法(X)为参比方法,对化学发光法(Y)进行评估。两种方法测定的回归方程式为y=1.034x-1.308,r2=0.958。当免疫透射比浊法的浓度为100、200、300mg/L时,它们的相对偏倚为2.1%、2.7%、3.1%。结论化学发光法与免疫透射比浊法测定偏倚比较评价均可接受,两种方法检测血清FN均具有良好的相关性,建议各临床实验室对不同方法建立参考值范围。
Objective To compare the immunoturbidimetric method with chemiluminescence method in the measurement of serum fibronectin(FN).Methods According to CLSI standardization document EP9-A2,8 serum samples were daily collected and tested for FN using immunoturbidimetric and chemiluminescence method for 6 days.Results The evaluation were done between reference method,chemiluminescence(Y) for evaluation.the determination of the regression equation were y=1.034x-1.308,r2=0.958.Conclusion Both immunoturbidimetric and chemiluminescence methods are acceptable in the measurement of serum FN.
