对于总补体活性的测定,目前一般仍沿用比较简便的50％溶血法,并以补体价CH_(50)来表示。我组在1974年冬采用CH_(50)方法测定250例健康人(献血员)血液中总补体含量,经过统计学方法处理,正常值为202单位/毫升,标准差37.58。并用同样方法在1975年春至1976年夏,对634例自身免疫病及其他免疫病、肝病、肾 For the determination of total complement activity, the simpler 50% hemolysis method is still used at present, and is expressed by the complement value CH_ (50). My group in the winter of 1974 using CH_ (50) method to determine the blood of 250 healthy people (blood donors) total complement content, after statistical methods, the normal value of 202 units / ml, the standard deviation of 37.58. And the same method in the spring of 1975 to the summer of 1976, 634 cases of autoimmune diseases and other immune diseases, liver disease, kidney
