C3 Complement near me in Kolkata








The C3 Complement is a blood test that measures the levels of C3, a protein that plays a critical role in the immune system's complement cascade. It helps diagnose autoimmune diseases and infections. It also assesses immune system health. This test is available at an affordable price in Kolkata with Tata 1mg labs.
The C3 Complement test is particularly useful for diagnosing and monitoring conditions associated with abnormal complement system activity. It is often recommended for individuals with unexplained symptoms of autoimmune or inflammatory disorders, such as joint pain, kidney problems, skin rashes, or frequent infections. It is also useful for assessing disease activity in conditions like SLE, as changes in C3 levels can reflect flare-ups or remission phases. If there is a family history of autoimmune diseases or genetic conditions that affect the immune system, this test may be recommended as part of a comprehensive health evaluation.
Overnight fasting (8 to 12 hours) is preferred for this test, however not mandatory.








What does C3 Complement measure?
The C3 Complement test measures the level of complement protein C3 in the blood. By measuring the levels of C3, doctors can assess whether there is an abnormal immune response, indicating an autoimmune disorder or chronic inflammation. A low level of C3 can be a sign of conditions like systemic lupus erythematosus (SLE), where the body attacks its own tissues. On the contrary, a high C3 level might suggest an acute inflammatory response or infection. This test is often used alongside other diagnostic tests to get a comprehensive picture of the immune system’s health and function.
