Synonym/Acronym:
Total hemolytic complement, CH50, CH100.

Rationale
To detect inborn complement deficiency, evaluate immune diseases related to complement activity, and follow up on a patient's response to therapy such as treatment for rheumatoid arthritis and systemic lupus erythematosus (SLE), in which complement is consumed at an increased rate.

Patient Preparation
There are no food, fluid, activity, or medication restrictions unless by medical direction.

Normal Findings
Method: Quantitative hemolysis for total complement; immunoturbidimetric for C3 and C4.
