What is the purpose of this test?
The Complement C3 Blood Test measures the level of a protein called complement C3 in your blood. Complement C3 is a vital part of the immune system, helping the body fight infections and supporting inflammation responses. This test is used to assess the activity and health of the immune system, providing valuable information for diagnosing and monitoring conditions related to immune system function.
Doctors use the Complement C3 Blood Test to investigate autoimmune diseases, such as lupus and rheumatoid arthritis, where the immune system attacks the body's own tissues. High or low levels of complement C3 can indicate different aspects of these diseases and help doctors decide on the appropriate treatment strategies. Additionally, this test can be part of monitoring certain kidney conditions, as complement C3 plays a role in kidney function and health.
