Objective: To evaluate the clinical performance of AQT90FLEX immunoassay analyzer in determination of D-dimer concentration in human whole blood.Methods: The EP5-A2 document of Clinical and Laboratory Standards Institute(CLIS) and Chinese standard of preliminary evaluation of quantitative clinical laboratory methods were referred to the correlation of D-dimer testing results by the AQT90 immune-assay analyzer and the CA 7000 coagulation analyzer,and the measurement data of D-dimer in 30 minutes,60 minutes and 90 minutes were compared.Results: At high concentration level,the with-run precision(CV) is 5.47%,the between-run precision is 6.72%;at low concentration level,the with-run precision is 8.07%,the between-run precision is 9.30%.The measured concentration and the estimated concentration has a correlation coefficient of r = 0.9958(P0.0001).The pollution-carrying rate is 0.77%.The measured data from AQT90 and CA7000 has a correlation coefficient of r=0.9935(P0.0001).Conclusion: The AQT90 FLEX had proper precision and linearity in determination of concentration.There is a high consistency between the testing results of AQT90 and CA7000.The evaluation showed that the AQT90 FLEX is applicable for clinical test.
