Serum IFN-γ and IL-17 levels in patients with AIHA compared to those in healthy donors Levels of IFN-γ and IL-17A were measured in serum samples taken from patients with AIHA (n=20) and matched healthy control donors (n=19). Bars indicate median values. There is no significant difference between the levels of IFN-γ in the two groups, but there is a significant increase in serum IL-17A in AIHA patients compared to healthy donors (**Mann-Whitney U test P<0.001). Where more than one serum sample was taken on different occasions from patients or donors, mean values are used.
