IgG4抗体将主导血吸虫病、淋巴丝虫病和过敏原免疫治疗后患者的IgG反应。与其他IgG亚类不同，IgG4不激活补体。IgA-IgG4联合缺乏与复发性化脓性感染有关。 由人血浆制备，经美国食品药品监督管理局要求的测试表明，人血浆对HBsAg、抗HCV、抗HBc无反应，对抗HIV 1和2呈阴性。 产品引用： Devaux JJ, Miura Y, Fukami Y, Inoue T, et al.

IgG4 antibodies will dominate the IgG response in schistosomiasis, lymphatic filariasis, and in patients after allergen immunotherapy. Unlike the other IgG subclasses, IgG4 does not activate complement. A combined IgA-IgG4 deficiency has been associated with recurrent pyogenic infections. Prepared from human plasma shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.
