ABSTRACT
ObjectiveTo provide a reference for the establishment and appliance of enzyme reference measurement of CK in China by comparing and analyzing the RELA results of CK in IFCC from 2006-2008. Methods The RELA samples of CK were measured according to the reference procedure for the measurement of catalytic activity concentration of CK (37 ℃) ,which had been published by IFCC. The EP5A2 protocol was used for evaluation of the imprecision and ERM was used for verification of the trueness. Results In RELA 2006, the result of sample A was (9. 896 ±0. 112) μkat/L, and the result of sample B was (4.953 ±0. 120) μkat/L. In RELA 2007, the result of sample A was (2.684 ±0.054)μkat/L, and the result of sample B was (8.798 μ0. 101) μkat/L. In RELA 2008, the result of sample A was (10. 523 ±0. 149) μkat/L,and the result of sample B was (10. 551 ±0. 141) μkat/L. The precision of the CK reference method in the year 2006 to 2008 was 0. 92%, 0. 86% and 0. 88% respectively, each of them is less than 1% and the results of ERMs were consistent with the certified value(1. 68 ± 0. 07)μkat/L,which verify the imprecision and accuracy of the reference method. Conclusions All of the results in the continuous three years were in the range of equivalence limits suggested by IFCC. The CK reference method suggested by IFCC has been established and it is getting better.
