Abstract:
Objective As a collaborator of Beijing Institute of Medical Device Testing for value assignment of state standard ma-terial candidate Cystatin-C ,we have used the internationally accepted reference material to assign value for state standard material candidate Cystatin-C ,and help Beijing Institute of Medical Device Testing get Cystatin-C national standard material certificate . Methods According to the target value and operational procedure of international reference material ERM-DA471 ,We have tested 6 dilutions of standard material candidate Cystatin-C on calibrated Hitachi 7180 immunoassay system .Results The results demon-strate good repeatability and commutability ,and have been accepted in calculating the final value for the candidate standard materi-al ,our data has assisted Beijing Institute of Medical Device Testing in passing the criteria and obtaining Cystatin-C national standard material certificate .Conclusion Compared to the data from all participating collaborators ,our results hit right on the target value , and no significant matrix effects have been observed .
