目的:探讨2种化学发光检测系统(A :Cobas e 411,B:Beckman Dxi800)测定血清糖链抗原(CA)19-9结果的可比性。方法按照EP9-A2方案,收集江门市中心医院2013年7月8~18日检测CA19-9的新鲜血清,取40份不同浓度新鲜患者血清在2种化学发光检测系统上进行CA19-9检测,对结果进行统计分析。以A系统为基准系统对B系统作临床可接受性能评价。结果2种系统检测结果经秩和检验差异无统计学意义(P>0.05)。B系统与A 系统相关回归方程为YB=1.0812XA -4.8484,r2=0.9622。CA19-9在给定结果25 U/mL和250 U/mL 处,B系统相对偏倚为11.28%和6.00%。以CA19-9生物学变异的最佳允许总误差22.1%为标准,临床全部可接受。结论使用Cobas e 411检测系统和Beckman Dxi800检测系统对CA19-9测定结果具有可比性。

Objective To compare the results carbohydrate antigen 19-9(CA19-9)determined by two different chemiluminescence immunoassay(CLIA) systems(A :Cobas 411 ,B :Beckman Dxi800) .Methods Referring to the EP9-A2 document ,40 serum samples from different patients were collected and CA19-9 levels were tested by the 2 different CLIA systems respectively .The collected data were processed by statistical analysis .A system was use as standard system to evaluate the acceptability of B system .Results There were no significant different between two different CLIA systems in rank sum test (P>0 .05) .Linear regression equations that B system for Asystem were YB=1 .0812 XA -4 .848 4 ,r2 =0 .962 2 .In Specified concentration 25 U/mL and 250 U/mL of CA19-9 ,B relative bias is 11 .28% and 6 .00% .By CA19-9 biological variation in the best total allowable error(TEa) 22 .1% for the standard . System B was completely acceptable .Conclusion There is comparability of two CLIA systems in the evaluation of clinical acceptability of CA19-9 and the difference between them is acceptable .
