Positive ratio of TRAb and ASST in CU combining hyperthyroidism group are higher than those of hyperthyroidism group.The level of sTSH in CU group are lower than controlling group.Conclusions:Thyroid autoantibodies show possible role in pathogenesis of chronic urticaria. Positive ratio of ASST in CU combining hyperthyroidism patients is higher. [Key words] Chronic urticaria;Hyperthyroidism;Thyroid autoantibodies; Autologous serum skin test
