摘要 目的观察直接法测定血清低密度脂蛋白胆固醇(LDL-C)的含量与其间接换算值的偏差。方法血脂测定方法按照标准化的要求进行。LDL-C用直接法测定和根据Friedewald公式换算,收集586例被检者血脂水平。结果在三酰甘油(TG)低于400 mg/dl(4.52 mmo/L)的血样中,直接法测定LDL-C的水平基本高于其间接换算值,偏差的范围为-59 mg/dl(-0.67mmol/L)^+48 mg/dl(0.54 mmol/L),差值的均值为+15.47 mg/dl(0.17 mmol/L)(P<0.001)。结论LDL-C含量直接测定与间接换算存在偏差,检测LDL-C含量需注意方法的偏差,建议采用统一的方法。
