    What is Complement 3 (C3) & Complement 4 (C4) Level Test?

    The C3 C4 Complement test is a blood analysis that measures the levels and activity of C3 and C4 proteins, key elements of the complement system. This system supports immune defence by detecting infections and removing harmful substances or damaged cells. The complement proteins function sequentially, triggering a response that enhances immune activity.

    This test is often advised for evaluating immune-related conditions or monitoring long-term illnesses. Deviations in C3 and C4 levels may suggest an underlying disorder. Unlike antibodies, which target particular infections, complement proteins offer broad protection by attacking harmful agents without prior exposure. In some cases, the immune system mistakenly attacks healthy tissues, as seen in autoimmune diseases, where this test plays a crucial role.

    It aids in diagnosing and monitoring conditions like lupus, rheumatoid arthritis, vasculitis, and kidney inflammation. It is also valuable for investigating frequent infections, swelling, or unexplained immune responses. In rare instances, a genetic deficiency in complement proteins may increase susceptibility to specific diseases.

    For individuals in Delhi, getting a C3 C4 Complement test at home is simple, with fast sample collection and prompt, accurate results.

    Complement 3 (C3) & Complement 4 (C4) Level Test Parameters

    The C3 C4 Complement test assesses two key components of the complement system—C3 and C4 proteins—by measuring their levels in the blood.

    These proteins are vital for immune defence, working to detect infections and regulate immune activity. The complement system is composed of nearly 60 proteins, with nine major ones labelled C1 through C9. Among them, C3 and C4 are most frequently analysed.

    One of the primary roles of the complement system is to enhance the immune response by increasing blood vessel permeability, which allows white blood cells to reach and neutralize infections. Any significant deviation in C3 or C4 levels may indicate an imbalance in immune function.

    Lower-than-normal C3 or C4 levels may point to conditions such as lupus, rheumatoid arthritis, or immune deficiencies, while elevated levels can be associated with infections, chronic inflammation, or other health concerns. In cases where C3 and C4 levels are abnormal, additional tests like CH50 may be conducted to assess overall complement system function.
