This test may be clinical useful to determine whether low complement levels indicate active consumption or deficiency. Determining complement consumption can also be used to monitor disease activity in conditions such as SLE Rhematoid arthritis

Notes

Serum samples may give falsely elevated levels of C3d, EDTA plasma must be used.
