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

    The C3 C4 Complement test is a blood examination that checks the presence and function of C3 and C4 proteins, which are vital components of the complement system. This system works alongside the immune system to defend the body against infections and eliminate damaged cells or harmful substances. These proteins work in a step-by-step process, where one activates another to create a chain reaction that helps the immune system respond efficiently.

    This test is recommended for suspicion of immune system disorders or monitoring of chronic diseases. Abnormal levels of C3 and C4 might indicate an underlying health issue. Unlike antibodies, which target specific infections, complement proteins act more generally, attacking invaders without needing previous exposure. Sometimes, the immune system mistakenly attacks healthy cells, leading to conditions like autoimmune diseases, where complement testing becomes useful.

    The C3 C4 test can help diagnose and track illnesses such as lupus, vasculitis, rheumatoid arthritis, or kidney inflammation. It is also useful for understanding why someone experiences frequent infections, swelling, or unexplained immune responses. In rare cases, individuals may have a genetic deficiency in complement proteins, making them more vulnerable to specific illnesses.

    If you are living in Bangalore, scheduling a C3 C4 Complement test at home is very convenient with quick sample collection and timely delivery of accurate results.

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

    The C3 C4 Complement test measures two important parameters: the levels of C3 and C4 complement proteins in the blood.

    Complement proteins are crucial for the immune system, helping the body defend against infections and regulate immune responses. The complement system consists of nearly 60 proteins found in the blood, with nine major complement proteins labelled C1 to C9. Among them, C3 and C4 are the most commonly tested complement proteins.

    The complement system assists the immune system by increasing blood vessel permeability, allowing white blood cells (WBCs) to reach the infection site and eliminating harmful cells. Low or high levels of C3 and C4 may signal immune system imbalances or autoimmune diseases.

    A low C3 or C4 level may indicate lupus, rheumatoid arthritis, or immune deficiencies, while a high level may suggest infections, chronic inflammation, or other underlying conditions. In some cases, doctors may also request a CH50 test to evaluate the overall function of the complement system when C3 and C4 levels are abnormal.

    • Who Should Get a C3 C4 Test?

    • Cautions Before taking a C3 C4 Test

    Before you take the C3 C4 test, you do not have to follow any special precautions.

    Why Take the Complement 3 (C3) & Complement 4 (C4) Level Test?

    • Lupus – A disease that affects different parts of the body, like the joints, skin, kidneys, and brain.

    • Rheumatoid Arthritis – A condition that leads to painful and swollen joints, especially in the hands and feet.

    • Unexplained Swelling and Pain – This may be a sign of an immune system problem.

    • Frequent Infections – Getting sick often might mean your immune system is not functioning properly.

    • Fatigue and Muscle Pain – Feeling tired all the time and experiencing muscle discomfort could indicate an underlying issue.

    The C3 C4 Complement test is also useful for:

    • Diagnosing Autoimmune Diseases : Low C3 and C4 levels may mean you have lupus, rheumatoid arthritis, or other immune disorders.

    • Monitoring Treatment Progress : If you are already being treated, this test helps your doctor understand if the treatment is effective.
