Like Bill says, antibody tests are not usually repeated.
Lupus activity is more often followed by 1) symptoms and 2) inflammation markers in the blood, and 3) sometimes, but not always, ANA
Inflammation markers include: The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and some others.
