Xc 408 esr monitor

Blood samples were collected on the day of urine sample collection. The immunoturbidimetric test was used to assess serum complement (C) and immunoglobulin antibodies (AU5421; Beckman Coulter, USA). Immunoblotting and immunofluorescence were used to detect serum autoantibodies. Erythrocyte sedimentation rate (ESR) was determined by the Westergren method (XC-408 ESR Monitor; Mindray, China).
Lupus nephritis (LN) was defined as clinical and laboratory manifestations that meet American College of Rheumatology criteria (56 (link)). Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) was used to assess disease severity (53 (link)).
