Complement factor C4 participates in activation by the classical route. A decrease in C4 is common, but complete absence is rare. A lowered concentration or the complete absence of C4 occurs in immunocomplex diseases, systemic lupus erythematosus (SLE), autoimmune thyroiditis and juvenile dermatomyositis.

Fortress Diagnostics manufactures C4 reagents designed for Hitachi 917, Olympus AU600/400/640/2700 and CA 180/270/400 Furuno/Daytona systems.
