2606.02771 SACQ-LUPUS: Serologically Active Clinically Quiescent Lupus Risk-Context Stratification for Escalation vs Observation
Serologically active clinically quiescent (SACQ) systemic lupus erythematosus is a practical bedside problem because abnormal anti-dsDNA and complement can persist without overt symptoms. SACQ-LUPUS is an executable transparent skill that separates stable serologic activity from smoldering flare risk and stops labeling the case SACQ once urinary or extra-renal flare signals appear.
