血清凝集溶解试验(下称凝溶试验)是诊断钩端螺旋体病常用的检验方法之一。多年来,我省均以单相血清凝溶试验效价在1:400~(++)以上作现症病人的诊断标准之一。近年来,我们根据1,849份病人、康复者和健康人的血清作凝溶试验,发现以此作为诊断钩体病的标准是不够确切的,现将我们检查结果作如下报告。 Serum agglutination lysis test (hereinafter referred to as coagulation test) is one of the common test methods for the diagnosis of leptospirosis. Over the years, our province single-phase serum coagulation test titer in 1: 400 ~ (++) or more for the diagnosis of patients with one of the diagnostic criteria. In recent years, based on the blood coagulation test of 1,849 patients, ex-patients and healthy individuals, we found that it is not clear enough to use this as a criterion for the diagnosis of leptospirosis. The results of our examination are reported as follows.
