Abstract
Objective To analyze the bias between sarcosine oxidase and Jaffe's methods for measuring the ser-um creatinine (Cre) .Methods According to the procedure described by the NCCLS approved guideline ,40 patients samples were analyzed in 5 operating days ,each sample was analyzed in duplicate by both enzymatic assay and Jaffe's kinetic assay .The duplicates were assessed for each method within the same run .The coefficient of correlation was calculated and the bias between two methods was calculated accordingly .Results The bias between the enzymatic as-say and Jaffe's kinetic assay were 1 .5% at 100 μmol/L ,6 .4% at 300 μmol/L and 7 .9% at 500 μmol/L for creati-nine .Conclusion The bias between two methods could be increased as the concentration of the serum creatinine in-creases .New reference range for creatinine should be established when new instrument or new reagent is applied .关键词
