| 摘 要： | 目的:对3种血清半胱氨酸蛋白酶抑制剂C试剂盒性能进行评价。方法:比较3种试剂盒的稳定性、精密度、准确度、线性范围及抗干扰能力。结果:3种Cys C试剂盒试剂空白CV分别为:2.56%、5.71%、0.62%;总精密度的CV分别为2.39%、8.50%、5.17%,不同试剂盒检测结果差异明显(P<0.001);平均回收率分别为96.65%、104.41%、62.80%;校准验证的偏差分别为:3.44%、-7.17%、3.05%;在0.5~6.0 mg/L范围内线性良好;黄疸、溶血和脂血对CysC测定均无明显干扰。结论:3种Cys C试剂盒性能均存在不足之处,尚不能满足临床实验室需求。
