(一)过去补体结合试验:1900年补体结合试验问世,1906年首用于麻风病。经多年研究,该试验清楚地证明:(1)麻风病人能产生很多抗体;(2)瘤型麻风血清滴度高,结核样型滴度低,两者区别明显;(3)麻风血清与那时分离出的大多数分枝杆菌抗原均可发生交叉反应。红细胞凝集试验:基本上证明了补体结合试验的发现。即麻风病人产生抗体的能 (A) the past combination of complement test: complement fixation test in 1900 came out, 1906 first for leprosy. After many years of research, the test clearly shows that: (1) leprosy patients can produce a lot of antibodies; (2) titers of leprosy titers high, low TB titer, the difference between the two obvious; (3) leprosy serum and that Most of the mycobacterial antigens isolated during the cross-reaction can occur. Erythrocyte agglutination test: Basically proved the discovery of complement fixation test. That leprosy patients can produce antibodies
