用固相放射免疫测验(SPRIA)检测甲型肝炎IgM抗体是近年才发展的技术。以此方法诊断甲型肝炎,不仅特异、敏感,而且只需急性期单份血清和单个稀释度,抗原不需太纯,24小时内即可得出结果,符合早期、可靠、简便的要求。鉴于国内尚无建立该技术及实际工作的需要,本实验室开展了对此技术的研究,现将结果报告如下。 Detection of Hepatitis A IgM by solid-phase radioimmunoassay (SPRIA) is a technology that has been developed in recent years. This method of diagnosis of hepatitis A is not only specific and sensitive, but only acute single serum and single dilution, antigen is not too pure, within 24 hours to reach the result, in line with early, reliable and simple requirements. In view of the fact that there is no need to establish this technology and its practical work in our country, our lab has carried out research on this technology. The results are reported as follows.
