摘要 目的:比较两种匀相法检测低密度脂蛋白胆固醇(LDL-C)的结果并分析甘油三酯(TG)的干扰作用。方法:分别用A、B两种匀相法试剂对40例患者的血清LDL-C以及不同TG水平下LDL-C的回收率和线性进行分析。结果:TG低于1.7mmol/L时A试剂LDL-C结果(2.47±0.57)mmol/L与B试剂结果(2.45±0.62)mmol/L无统计学差异(P<0.05);TG高于1.7mmol/L时A试剂LDL-C结果[2.66(1.82~3.42)mmol/L]显著高于B试剂结果(1.97±0.69)mmol/L,P<0.01,两者差值与TG浓度显著相关(r=0.937,P<0.01);两种试剂LDL-C回收率和线性无显著差异。结论:TG浓度对其中至少一种试剂LDL-C检测有严重干扰作用,而且这种干扰作用不能通过室内质控或稀释样品的方法得到纠正。
