摘要 目的对胶乳增强免疫比浊法测定血清胱抑素C进行方法学评价,验证其临床实用性。方法依据美国临床实验室标准化委员会文件要求对血清胱抑素C胶乳增强免疫比浊法进行精密度、线性范围、灵敏度和抗干扰性分析。结果胶乳增强免疫比浊法测定血清胱抑素C的批间变异系数小于3%,检测线性范围为0.42~7.54mg/L,最低检测限为0.034mg/L,而且血清中血红蛋白(10g/L)、胆红素(600mg/L)、脂肪乳剂(10g/L)、三酰甘油(15g/L)和类风湿因子(1 200IU/mL)因子对检测结果无明显干扰作用。结论乳胶增强透射免疫比浊法能定量检测人血清中的胱抑素C,符合临床实验室常规检测的需要,为临床评价肾功能提供了一项简便、可靠、实用的手段。
