Total Complement (CH50) concentration is an overall measure of the complement system. Decreased concentrations are observed in patients with complement factor deficiencies and disease activity, e.g., systemic lupus erythematosus (SLE) and immune complex disease.

CH50 values below the reference range may indicate a deficiency in one or more of the components of complement. To obtain more definitive information, abnormal specimens should be assayed for levels of the individual components (C1 to C9).
