The C4 – Complement 4 test measures the level of Complement component 4, a protein that plays a crucial role in the classical complement pathway of the immune system. Complement proteins help the body fight infections and clear immune complexes.
Reduced C4 levels are commonly seen in autoimmune diseases such as systemic lupus erythematosus (SLE), immune complex–mediated vasculitis, and hereditary angioedema. Elevated levels may be observed in acute inflammation or infection. The C4 test is usually interpreted along with C3 complement levels and other autoimmune markers to assess immune activity and disease progression.
