A technique for detecting IgM rubella antibodies by immunofluorescence was developed. Total serum IgG was removed by prior immunoabsorption with anti-gammaFc. This prevents interference by rheumatoid factors in the serum. The test appeared sensitive and specific in sera of rubella convalescents and infants with congenital rubella.
开发了一种通过免疫荧光检测IgM风疹抗体的技术。通过用抗γFc进行预先免疫吸附去除血清中的总IgG。这可防止血清中类风湿因子的干扰。该试验在风疹恢复期患者和先天性风疹婴儿的血清中显示出敏感性和特异性。
