酸溶血试验也称为Ham试验,是用于诊断阵发性睡眠性血红蛋白尿症(PNH)的一项常用试验。阵发性睡眠性血红蛋白尿症患者的红细胞膜对补体敏感,当加入到用稀盐酸酸化的血清中(含有补体及备解素),经孵育后可有溶血现象发生,此为阳性结果。正常人则不发生溶血现象,为阴性。该实

1酸化血清溶血试验原理:阵发性睡眠性血红蛋白尿症(PNH)患者体内存在对补体敏感的红细胞。酸化血清溶血试验,也称Hamtest,即红细胞在___而正常红细胞不被溶解,无溶血现象。结果:阴性。___。阳性主要见于PNH,某些自身免疫性溶血性贫血发作严重时可呈阳性。PNH患者血清溶血,左为正常对照 2酸化血清溶血试验原理:阵发...
Furthermore, anti-human P mAb potently and dose-dependently inhibited acidified serum-induced hemolysis (Ham's test) of abnormal erythrocytes from paroxysmal nocturnal hemoglobinuria (PNH) patients. In contrast to erythrocytes rescued by anti-human C5 mAb treatment in the Ham's test, non-lysed PNH...
