The complement system consists of almost 60 proteins that work together to promote immune and inflammatory responses, destroy and remove foreign pathogens like bacteria and viruses, as well as damaged “self” materials (e.g. cells and proteins). C3 and C4 are the most frequently measured complement proteins. These tests measure the amount or activity of complement C4 in the blood.

Anti-CCP are autoantibodies your immune system produces. Autoantibodies can cause disease by attacking the body's healthy cells by mistake. Anti-CCP attacks healthy tissues in the joints, which can cause pain, swelling, and stiffness. If CCP antibodies are present in your blood, it can be a sign of rheumatoid arthritis. Anti-CCP and another test, called an RF test, are usually done to diagnose rheumatoid arthritis.

Double-stranded DNA antibodies (ds-DNA Ab) are found primarily in systemic lupus erythematosus (SLE) and are important but not entirely sufficient for diagnosing the condition. Such antibodies are present in 80% to 90% of SLE cases. They are also found in smaller fractions of patients with other rheumatic disorders and chronic active hepatitis, mononucleosis, and biliary cirrhosis.
