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

    The C3 C4 Complement test evaluates the levels and role of C3 and C4 proteins in the bloodstream. These proteins are essential parts of the complement system, a key component of the immune defence that works to detect infections, clear out harmful substances, and support overall immunity. Acting in a sequence, complement proteins trigger a response that strengthens the body’s ability to fight threats.

    This test is commonly ordered for individuals suspected of having immune-related disorders or those with chronic illnesses. A significant rise or fall in C3 and C4 levels may indicate an underlying health condition. Unlike antibodies, which recognize and neutralize specific infections, complement proteins provide a more general defence by attacking foreign invaders without prior sensitization. Autoimmune diseases, where the immune system targets healthy cells, often require complement testing for diagnosis and management.

    The test helps in assessing conditions like lupus, rheumatoid arthritis, vasculitis, and kidney disorders. It is also useful in understanding the cause of recurring infections, unexplained swelling, or unusual immune responses. In rare cases, some people may have inherited deficiencies in complement proteins, increasing their susceptibility to infections.

    Those in Hyderabad can easily schedule a C3 C4 Complement test from home, ensuring swift sample collection and timely results.

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

    The C3 C4 Complement test evaluates the concentration of two crucial proteins—C3 and C4—in the bloodstream. These proteins belong to the complement system, a group of nearly 60 immune-related proteins, of which C1 to C9 are the most significant. C3 and C4 are routinely tested due to their vital role in immune function.

    The complement system aids immune defence by enhancing blood flow to infection sites, allowing white blood cells to target and destroy harmful pathogens. Imbalances in C3 or C4 levels may indicate immune dysregulation or autoimmune diseases.

    Low C3 or C4 levels can be associated with conditions such as lupus, rheumatoid arthritis, or immune deficiencies, whereas elevated levels may point to infections, chronic inflammation, or other medical concerns. If abnormalities are found, a CH50 test may be advised to assess the complement system’s overall functionality.
