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

    A C3 C4 Complement test assesses the presence and functionality of C3 and C4 proteins, which are key to the complement system’s role in immune defence. This system detects and eliminates harmful pathogens while assisting in the removal of damaged cells. The complement cascade involves a stepwise activation, enhancing immune response efficiency.

    This test is useful in diagnosing immune-related conditions or monitoring chronic illnesses. Deviations in C3 and C4 levels may suggest an underlying issue. While antibodies specifically recognize infections, complement proteins launch a more general attack, acting independently of prior exposure. In cases of autoimmune diseases, where the immune system mistakenly targets the body’s tissues, complement testing becomes essential.

    The test can help detect disorders such as lupus, rheumatoid arthritis, vasculitis, and kidney inflammation. It is also valuable for individuals who experience recurring infections, unexplained immune responses, or persistent swelling. Some rare genetic conditions can lead to complement deficiencies, increasing vulnerability to infections.

    In Bangalore, scheduling a home-based C3 C4 Complement test is simple, ensuring fast sample collection and reliable results.

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

    The C3 C4 Complement test determines the blood levels of two critical proteins, C3 and C4, which are integral to the immune system’s complement pathway. This pathway consists of nearly 60 proteins, with C1 to C9 being the key ones. C3 and C4 are most frequently tested due to their direct involvement in immune regulation.

    These proteins help immune cells combat infections by increasing blood vessel permeability, ensuring that white blood cells can access infection sites more efficiently. Any fluctuation in their levels may point to an immune system imbalance.

    A reduced C3 or C4 level may indicate lupus, rheumatoid arthritis, or an immune deficiency, whereas elevated levels may be associated with infections, chronic inflammation, or other medical issues. In cases of abnormal C3 and C4 findings, a CH50 test may be conducted to further evaluate the complement system’s overall functionality.

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

    This test helps assess immune health and is recommended if you have:

    • Fatigue and Muscle Pain – Constant tiredness and muscle discomfort could suggest an immune-related problem.

    • Unexplained Swelling and Pain – Persistent inflammation could be linked to immune system dysfunction.

    • Lupus – A condition that affects multiple organs, including the joints, skin, and kidneys.

    • Frequent Infections – If you often fall ill, it may indicate an issue with immune function.

    • Rheumatoid Arthritis – An autoimmune disorder that leads to joint pain and stiffness.

    How This Test Helps

    • Diagnoses Autoimmune Disorders – Low C3 and C4 levels can be associated with lupus, rheumatoid arthritis, and other immune-related conditions.

    • Evaluate Treatment Progress – If you are already on medication, this test helps determine if the treatment is working.

    • Detects Immune Deficiencies – It helps identify irregularities in immune response.

    Early testing ensures timely diagnosis and treatment, improving overall health outcomes.
