| 摘 要： | 目的评价免疫固定电泳、尿液轻链定量及血清游离轻链检测在多发性骨髓瘤（MM）患者轻链检测中的价值。方法用速率散射比浊法进行重链、轻链及游离轻链定量,用蛋白电泳及免疫固定电泳法对M成份做定性分析,对多发性骨髓瘤患者轻链型21例,完整型29例（其中IgGI、gA型19例;IgD型10例）标本分别做免疫固定电泳,尿轻链定量及游离轻链检测,然后比较三种方法的检出率和灵敏度。结果对于轻链型骨髓瘤患者,免疫固定电泳、尿轻链定量及血清游离轻链检测三种方法的轻链检测阳性率分别为90.5%（19/21）;80.9%（17/21）;100%（21/21）。对于完整型骨髓瘤患者三种方法的游离轻链检测（免疫固定电泳法检测与重链结合的单克隆轻链的阳性率100%）阳性率分别为20.7%（6/29）;41.4%（12/29）;82.7%（24/29）。结论血清游离轻链检测较另外两种方法检测游离轻链更为灵敏,其与免疫固定电泳法结合检测对多发性骨髓瘤患者的明确诊断、疗效观察及改善预后起重要作用。
