Objective :To determine the relevance of microelements in Xuesaitong Injection and erythrocyte abnormal hemolysis induced by the injections.Method :25 kinds of metal microelements of different batches injections were assayed by ICP-MS method,and the difference between normal hemolysis group and abnormal hemolysis group was compared.Results :No difference existed between normal hemolysis group and abnormal hemolysis group,and the content of Zn of normal hemolysis group was higher than that of the normal hemolysis group.Conclusion :The abnormal hemolysis induced by Xuesaitong Injection was irrelevant to heavy metals.
