两种糖化血红蛋白临床检验方法的一致性评价

Consistency Evaluation of Two Kinds of Clinical Examination Methods for Glycated Hemoglobin

目的使用线性回归方法和Bland-Altman分析法评估两种糖化血红蛋白检测系统检测结果的相关性和一致性。方法选取99例患者全血样本,分别使用糖化血红蛋白对照系统和考核系统检测,对两种检测系统的检测结果进行相关性分析与Bland-Altman分析。结果对照系统和考核系统间的决定系数R2=0.9779(P=0.0000),表明两种检测系统的测量结果之间具有显著的相关性。Bland-Altman一致性分析结果表明:界外点数(比率)4.04%。结论两种检测系统对糖化血红蛋白检测结果一致性良好。

Objective Consistency evaluation of two kinds of clinical examination for Glycated Hemoglobin(HbAlc)with linear correlation and Bland-Altman analysis.Methods Control system and assessment system were used to test the HbAlc of venous blood samples from 99 cases of patients,the results are analysed with correlation and Bland-Altman analysis.Results The determination coefficient R2 is 0.9779,which shows that there is a good relationgship between control system and assessment system;Bland-Altman consistency analysis shows that the maximum points out(ratio)is 4.04%.Conclusion There is a good consistency for HbAlc between control system and assessment system.
