目的比较HPLC和微生物法测定万古霉素血药浓度的差异。方法30名病人静脉滴注万古霉素1.0 g,1次·d-1,分别用HPLC和微生物法测定用药前后的血药浓度。结果HPLC法在5.0~80 μg·mL-1浓度内线性关系良好,回收率97.3%~101.6%,日内、日间RSD分别为1.74%~4.06%和1.22%~4.21%;微生物法线性范围在5.0~60 μg·mL-1,回收率:98.2%~100.8%,日内、日间RSD分别为4.22%~5.51%和4.59%~6.49%。结论2种测定方法回收率和精密度均符合要求,测得的血药浓度无显著性差异。 |

Abstract: |
OBJECTIVE To compare HPLC and microbiological assay for determination of the content of vancomycin in human serum. METHODS Thirty patients were given 1.0 g vancomycin by infusion,q.d..The serum concentration were determined by HPLC and bioassay,respectively. RESULTS The calibration curve of HPLC was within the range of 5.0-80.0 μg·mL-1. The recovery of HPLC method was 97.3% to 101.6%,within-day and day-to-day RSD were 1.74%-4.06%,and 1.22% -4.21%, respectively. The calibration curve of microbiological assay was linear in the range of 5.0-60.0 μg·mL-1. The recovery of microbiological assay was 98.2%-100.8%,within-day and day-to-day RSD were 4.22%-5.51% and 4.59%-6.49%,respectively. CONCLUSION The recovery and precision of the both methods are similar. There were no significant differences. |
