Complement tests, most commonly C4 are used to determine whether deficiencies or abnormalities in the complement system are causing, or contributing to, a person's disease or condition. Complement plays several functions in immunity. It can poke holes in bacteria, kill bacteria that are first targeted by antibodies, or, working with antibodies, point out which bacteria need to be engulfed by white blood cells. Without sufficient complement, the body is prone to frequent infections, like pneumonia or meningitis, or other illnesses, including autoimmune diseases, like systemic lupus erythematosus. Complement testing may be used to diagnose and monitor the activity and treatment of acute or chronic autoimmune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis. Monitor immune complex-related diseases and conditions such as glomerulonephritis (a kidney disorder), serum sickness, and vasculitis.
