目的:比较四种胃蛋白酶原检测试剂的性能。方法:使用Beckman Coulter AU5800全自动生化分析仪,采用免疫比浊法,对两种国产和两种进口蛋白酶原检测试剂的校准和质控、精密度、线性范围、检测灵敏度、前带反应影响和抗干扰能力进行比较。结果:四家公司的校准和质控指标均达到合格标准,两家进口试剂变异系数较小,在线性、准确性、灵敏度、前带反应等指标全面领先。结论:综合各项指标判断,目前使用的胃蛋白酶原检测试剂以两种进口产品性能为佳,国产品尚有一定差距。
Objective: To compare the performance of four pepsinogen assay reagents. Methods: The Beckman Coulter AU5800 automatic biochemical analyzer was used to determine the calibration and quality control of two domestic and two imported protease detection reagents, precision, linear range, detection sensitivity, Anti-interference ability to compare. Results: The calibration and quality control indexes of the four companies all reached the qualified standard. The coefficient of variation of the two imported reagents was small, leading in the aspects of linearity, accuracy, sensitivity and frontal reaction comprehensively. Conclusion: Judging from the various indicators, the currently used pepsinogen detection reagent is better than the two imported products, and there is still a certain gap between domestic products.
