摘要 目的通过比较和分析不同的自身抗体吸收法,寻找一个合适、经济和有效的自身抗体吸收法,以更好地筛选和鉴定自身免疫性溶血性贫血(AIHA)患者血清中的同种抗体。方法取20例AIHA患者血清,分别采用木瓜蛋白酶自身红细胞温吸收法、聚乙二醇(PEG)自身红细胞温吸收法、木瓜蛋白酶同种红细胞吸收法和PEG同种红细胞吸收法对自身抗体进行吸收,比较吸收时间、吸收次数、吸收后血清抗体鉴定结果。结果 PEG同种红细胞吸收法平均每例吸收1.8次,明显低于木瓜蛋白酶同种红细胞法的平均值4.1次(P<0.05)。两种方法平均吸收时间分别为90.0 min和225.1 min,二者比较差异有统计学意义(P<0.05)。两种吸收方法同种抗体的特异性、效价检测结果一致,均为RH系统的同种抗体。结论 PEG法可以快速、经济和有效去除AIHA患者血清中的自身抗体,便于同种抗体鉴定。
