In serum of AIH patients, the positive rate of RF is closely correlated with those of 3 types of autoantibody including ANA,ASMA and AMA. It suggests that serum RF is a reference item of experimental diagnosis for AIH.

• AIH患者血清中RF阳性率与其ANA、ASMA和AMA3种自身抗体的阳性率密切相关,提示RF与ANA、ASMA和AMA均可作为实验诊断AIH的辅助参考指标。
