Abstract:
Objective To review the performance of the IFCC enzyme reference methods in China laboratories and to evaluate the competence of enzyme reference measurement in China.Methods The Intemational Federation of Clinical Chemistry and Laboratory Medicine(IFCC)enzyme reference methods were performed in 8 China laboratories.Reference procedures were developed by each laboratory and the performances were evaluated.The Clinical and Laboratory Stadards Institute(CLSI)EP-5 protocol was used for the evaluation of precision and certified reference materials(CRMS)were used for the verification of trueness.Seven of the 8 laboratories participated in the 2006 IFCC external quality assessment program for reference laboratories(RELA)for the assessment of the measurement performance.Results Within-run CVs of less than 1.5%and between-run CVs of less than 2%were achieved bv all the China laboratories.Results on CRMs by some of the laboratories agreed with the certified value within the stated uncertainty.In the 2006 RELA,the averages and the interlaboratory CVs of the China laboratories were similar to those of international laboratories.Conclusion A preliminary enzyme reference method laboratory network has been established in China.
