Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect multiple organs, including the skin, joints, kidneys, heart, and nervous system, making early and accurate diagnosis critical for effective management. At Southern Medical Supplies Limited (SMSL), we offer a full suite of SLE diagnostic tests designed to detect disease-specific autoantibodies such as ANA, anti-dsDNA, anti-Smith, and extractable nuclear antigens. Our portfolio includes ELISA, immunoblot, immunofluorescence, molecular, and biomarker assays from trusted global partners including EUROIMMUN, Ansh Labs, Randox, Streck, and Bio-Rad, ensuring exceptional sensitivity, specificity, and reproducibility. These advanced tools support clinicians in confirming diagnosis, monitoring disease activity, and tailoring therapy, ultimately improving care and long-term outcomes for patients living with lupus.
