两个厂家α_1微球蛋白试剂性能评估和比较

The performance evaluation and comparison between two manufacturers for α_1-MG

目的比较国内2个厂家α1微球蛋白测定试剂(α1-MG)在同一台生化分析仪上的检测结果。方法用两种试剂进行α1-MG测定,并对两种试剂的精密度、检测范围、功能灵敏度、准确度、试剂稳定性和临床比对等结果进行评价。结果 A厂家的试剂在功能灵敏度、测定范围和尿液测定α1-MG比B厂家更佳,血尿同测能够更好地满足临床需求,为临床应用提供极大的方便,其他指标A厂家和B厂家差异不大。结论 A厂家生产的α1-MG测定试剂盒具有更高的性价比,优势明显。

Objective To compare the test results about α1-microglobulin（α1-MG） reagent between two manu- facturers in the same biochemical analyzer. Methods α1-MG was tested by two reagents . The precision,detection range,functional sensitivity, accuracy, reagent stability were evaluated. Results The reagents of A manufacturer＇s functional sensitivity,detection range and urine determination of α1-MG were better than the B manufacturer＇ s. And simultaneous determinations of blood and urine could met the clinical demand, which could greatly facilitate clinical application,other indices were not obviously different with B manufacturer. Conclusion Reagent of α1-MG from A manufacturer has good price and quality.
