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

    The C3 C4 Complement test is designed to measure the quantity and function of C3 and C4 proteins in the blood. These proteins are integral to the complement system, which works alongside the immune system to combat infections and clear out damaged cells. Their activation follows a stepwise process, amplifying the body’s natural defence mechanisms.

    Doctors often recommend this test when evaluating potential immune dysfunctions or monitoring chronic illnesses. Any imbalance in C3 and C4 levels may signal an underlying medical issue. Unlike antibodies, which are trained to recognize specific threats, complement proteins provide a broader immune response, acting without prior exposure. In autoimmune diseases, where the body mistakenly attacks its tissues, complement testing plays a crucial role.

    This test aids in diagnosing and tracking diseases such as lupus, vasculitis, rheumatoid arthritis, and kidney inflammation. It is also beneficial in identifying causes of frequent infections, inflammation, or unexpected immune reactions. In rare cases, genetic deficiencies in complement proteins can make individuals more vulnerable to infections.

    For those in Mumbai, arranging a C3 C4 Complement test at home is a convenient option, offering easy sample collection and prompt, precise results.

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

    This test measures the levels of C3 and C4 proteins, two essential components of the complement system, which supports immune defence by identifying and eliminating threats.

    The complement system consists of nearly 60 proteins in the blood, with nine major proteins labelled C1 to C9. Among them, C3 and C4 play a crucial role in strengthening immune responses. They assist the immune system by increasing blood vessel permeability, enabling white blood cells to reach infected areas and destroy harmful agents.

    Abnormalities in C3 and C4 levels may indicate immune dysfunction or inflammatory diseases. Low levels are often linked to lupus, rheumatoid arthritis, or immune deficiencies, while higher levels may suggest infections, chronic inflammation, or other underlying disorders. If C3 and C4 results are abnormal, a CH50 test may be used to evaluate overall complement system function.
