Complement 4 (C4) (BC0172)

Description

Complement 4 (C4) is a blood test used to measure the level of C4, a protein of the complement system that plays an important role in immune response and inflammation. This test is commonly used in the evaluation and monitoring of autoimmune disorders such as systemic lupus erythematosus (SLE), immune complex diseases, hereditary angioedema, and certain inflammatory or infectious conditions. Abnormal C4 levels help clinicians assess disease activity, immune system function, and response to treatment when interpreted with other complement components.
