Abstract

Abstract: Objective To evaluate the effects of Roche Cobas E601 automatic electrochemiluminescence immunoassay analyzer for determining CEA. Methods To analyze E601’s measurement precision, accuracy, measurement range, reference interval and carryover rate of CEA, verification experiments were taken to measure. Results The high and low values of CV of inter-assay were 4.96%and 4.38%, and between-day CV were 4.99% and 4.81%; 5 quality-control serum’s relative bias were between 1.49%-3.57%; there was good linear relationship between measured values and expected values;there was 96.3%of the measurement data in the recommended reference interval;carryover rate range was 0.12%. Conclusion Roche Cobas E601 analyzer is stable, precise and accurate.

Key words: electrochemiluminescence immunoassay analyzer, performance evaluation, CEA
