Is your Dr treating you for how you feel? That is more important than what your blood levels show.
Part of the reason I say this is because none of my rheumies have ever even tested C3/C4. They've watched disease activity from 1) reported symptoms, and 2) blood inflammation markers.
Are you under any ongoing treatment? Plaquenil, Prednisone, Cellcept, Imuran, MTX, Benlysta, anything?
