ABSTRACT
Cyclosporine A is widely used in organ transplantation and autoimmune diseases . Due to the obvious differences in metabolism between individuals ，the dosage should be adjusted according to the patient ’s blood concentration during clinical use . But the blood concentration does not reflect accurately its clinical prognosis . This article focuses on the four laboratory examination indexes following aspects ：the cyclosporine A concentration of peripheral blood mononuclear cells ，calcineurin activity ，T cell function and metabolite concentration of cyclosporine A . The relationship between them and the pharmacokinetics of cyclosporine and clinical prognosis were reviewed . It’s found that the above indicators have a certain predictive effect on the clinical prognosis of patients receiving cyclosporine A ，which can make up for the insufficiency of blood drug concentration monitoring ，and the clinical practicability needs to be further improved .
