Connective tissue diseases, including systemic lupus erythematosus, systemic sclerosis, Sjögren’s syndrome, and mixed connective tissue disease, often present with overlapping and complex clinical features that demand precise diagnostic tools. At Southern Medical Supplies Limited (SMSL), we provide a comprehensive range of connective tissue disease diagnostic tests that detect key autoantibodies and biomarkers with high reliability. Our portfolio includes ELISA, immunoblot, immunofluorescence, molecular, and biomarker assays from globally recognized partners such as EUROIMMUN, Ansh Labs, Randox, Streck, and Bio-Rad, ensuring outstanding sensitivity, specificity, and reproducibility. These advanced solutions empower clinicians to confirm diagnoses, monitor disease activity, and personalize treatment strategies, ultimately improving patient outcomes in complex autoimmune and multisystemic conditions.
