Remarks: C3c is used in monitoring autoimme diseases activity. Congenital C3c deficiency may be associated with pyogenic infections and/or with compromise of the immune system. It is particularly useful to assess disease activity in autoimmune diseases (C3c is decreased in SLE). High C3c levels may indicate activation of the immune system due to inflammatory process and/or infections.
