鼠疫流行病学血清学调查方法除经典间接血凝试验(IHA)外,放免沉淀—SPA法、富集血凝法等已广泛应用于鼠疫特异性F_1抗体的检查。但在实际工作中同一份标本同时应用反向间接血球凝集试验(RIHA法)作特异性抗原检查将有助于查源效果。国内已有人证实该法有较高的特异性和敏感性。鉴此,本文对该法在监测工作中的应用价值提出一些看法,现报告如下。 Epidemiological serological survey methods of plague In addition to the classical indirect hemagglutination test (IHA), the immunoprecipitation-SPA method and the enrichment hemagglutination method have been widely used in the examination of the plague-specific F_1 antibody. However, in practice, the same specimen with reverse indirect hemagglutination test (RIHA method) for specific antigen test will help to check the source effect. Some people in the country have confirmed that the law has higher specificity and sensitivity. In view of this, this article puts forward some opinions on the application value of this law in monitoring work. The report is as follows.
