Complement 3 Test (C3)

Complement 3 (C3) test is a blood test that measures the level of the complement protein C3 in the bloodstream. The complement system is a group of proteins that play a vital role in the body's immune response to infections and other foreign substances. C3 is the most abundant complement protein in the bloodstream and is involved in a variety of immune functions, including inflammation, opsonization, and clearance of immune complexes.

This test is typically ordered to help diagnose and monitor various autoimmune diseases, such as lupus, as well as certain kidney and liver diseases. It may also be ordered to monitor treatment progress for these conditions.

The C3 test is a simple blood test that requires no special preparation. A healthcare professional will collect a blood sample, usually from a vein in the arm. The sample will be sent to a laboratory for analysis, and results are usually available within a few days.

If you have symptoms of an autoimmune disease or are being treated for one, your healthcare provider may order a C3 test along with other tests to help diagnose and monitor your condition. Monitoring your C3 levels can help your healthcare provider determine if your treatment plan is working and if any adjustments need to be made.
