Abstract:
Objective To investigate the comparability of test seven tumor marks results of two electrochemiluminescence immu-noassay analyzer between Roche Cobas E411 and Cobas E601 .Methods According to United States Clinical and Laboratory Stand-ards Institute (CLSI) EP9-A2 document ,E411 was acted as comparison method (X) and E601 was as the experimental method (Y ) .Alpha fetoprotein (AFP ) ,carcinoembryonic antigen (CEA ) ,carbohydrate antigen125 (CA125 ) ,carbohydrate antigen199 (CA199) ,carbohydrate antigen153(CA153) ,total prostate specific antigen(TPSA) and free prostate specific antigen(FPSA) levels of patient samples were tested and the results were analyzed .Results The correlation between the two systems was good and the bias was acceptable in the medical decision level .Conclusion Two systems have good concordance in detecting the seven tumor markers ,w hich can meet the clinical need .
