摘要 目的 对免疫分离法测定血浆脂蛋白残粒胆固醇 (RLP C)进行方法学评价 ,并探讨其临床应用价值。方法 分析免疫分离法测定血浆RLP C的精密度、准确度、干扰因素 ,并将该法与超速离心法 (UC)进行比较 ,同时用该法测定 80例正常人、70例冠心病患者、72例 2型糖尿病患者和2 5例Ⅲ型高脂蛋白血症患者空腹血浆RLP C水平。结果 免疫分离法测定血浆RLP C的批内CV为 2 .78%~ 4 .98% ,批间CV为 3.99%~ 7.5 7% ,RLP C浓度 2 .4 4mmol/L以下时线性良好 ,r =0 .992。分析灵敏度为 0 .0 5mmol/L ,回收率为 92 .1%~ 98.3% ,免疫分离法 (X)与超速离心法 (Y)具有良好的相关性 ,Y =1.0 2 2X +0 .0 2 1,r =0 .989。甘油三酯 (TG) <15 .3mmol/L ,血红蛋白 (Hb) <5g/L ,低密度脂蛋白胆固醇 (LDL C) <7.0mmol/L ,高密度脂蛋白胆固醇 (HDL C) <3.0mmol/L ,胆红素 <342 μmol/L ,抗坏血酸 <15 0mmol/L时对方法无显著干扰。冠心病患者、2型糖尿病患者和Ⅲ型高脂蛋白血症组空腹血浆RLP C分别为 (0 .4 4 5± 0 .2 5 1)mmol/L、(0 .336± 0 .172 )mmol/L和(0 .878± 0 .6 72 )mmol/L ,均显著高于正常人 [(0 .190± 0 .0 70 )mmol/L],P <0 .0 0 1。结论 免疫分离法测定RLP C操作简单 ,结果准确可靠 ,精密度好 。 Objective To evaluate an immunoseparation assay for quantitative determination of remnant lipoprotein cholesterol in plasma and its clinical application .Methods Its precision,accuracy,specificity and interference were analyzed.The results of immunoseparation assay were compared with the one of ultracentrifugation(UC) .RLP-C concentration was determinated with immunoseparation assay in 80 heathy individuals,70 patients with coronary heart disease,72 patients with non-insulin -dependent diabetes mellitus a...
