Complement Level - C3 in Bowenpally, Hyderabad

The Complement Level test, also known as the C3 test, tracks the activity of the C3 protein in the blood. The complement system in the blood consists of nearly 60 proteins usually expressed on the surface of specific cells or blood plasma. Among these, there are nine major complement proteins named C1 to C9. These cells portray different functions, helping the complement system play an integral role in the body's immune function.

C3 is a protein responsible for activating the complement system. During the invasion of bacteria or viruses, the C3 protein is cleaved into two smaller pieces, one of which interacts with other proteins on various cells to trigger the response of the complement system. The protein also ensures that it activates the complement system only at locations affected by the pathogen to avoid host tissue damage.Abnormal C3 protein levels may affect the immune response and cause infections.

The complement level – C3 test is a blood test to detect the activity of the C3 protein and hence gauge the body's immune response. The test also acts as a marker to detect autoimmune conditions like Lupus in a patient. When the C3 protein levels are low, the complement system may attack harmless tissue, which could lead to tissue damage. The doctor can use the complement level- C3 test results to understand the working of the complement system. It might also help detect the presence of other immune disorders like glomerulonephritis and vasculitis.

The procedure for the test resembles a standard blood test. The clinical lab technician draws blood from the vein in the arm, usually at the bend of the elbow. The subsequent blood testing can help track the activity and levels of C3 protein. The lab may also test the levels of the C3 protein against other major complement proteins in the blood.
