Abstract:
Objective Study on the traceability of serum enzyme ass ays by testing enzyme reference material in clinical laboratories. Methods 50 laboratories were involved in this survey. One enzyme reference material was send to each participate lab. The reference material was tested by use of routine method and the results were recorded. All lab data were processed with computer. Results Compare with the target values, the bias of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK) and lactate dehydrogenase (LD) assays were 6 3%, 5 5%, -5 9% and -5 0% respectively, the bias of alkaline phosphatase (ALP) assays was -36 6. The inter laboratory coefficient variation of the amylase assay was 29 2%. Conclusions The results of enzyme assay in clinical laboratories could be traced to the international reference material.
