OBJECTIVE To analyze the consistency and correlation between UHPLC-MS/MS and chemiluminescence microparticle immune assay (CMIA) in measuring vancomycin concentration in serum.METHODS The concentration of vancomycin was measured by UHPLC-MS/MS and CMIA methods respectively in 95 serum samples of patients receiving vancomycin treatment. A correlation analysis and an agreement analysis were conducted for the two methods used linear regression and Bland-Altman method. RESULTS Based on the results of UHPLC-MS/MS(x) and CMIA(y), the linear regression equation was determined as follows: y=1.088x+0.174. Spearmen correlation analysis indicated a significant correlation between the results by the two methods (P<0.05), and the Spearmen correlation coefficient was 0.969 1. There was statistical difference between vancomycin serum concentrations measured by these two methods. The result was higher by CMIA compared with UHPLC-MS/MS. CONCLUSION The results of the two methods can be calculated to one another by equation, which provides reference for the formulation of clinical individualized medication plan.
