The Complement, Total (CH50) Test measures the overall activity of the complement system—an important part of the immune system that helps the body fight infections. Abnormal levels may be associated with autoimmune conditions, chronic infections, or inflammatory disorders. Symptoms that may prompt testing include persistent fatigue, frequent infections, joint pain, swelling, or unexplained inflammation.
