Anti-GBM disease (Goodpasture’s syndrome) is a life-threatening autoimmune condition marked by rapidly progressive glomerulonephritis and, in many cases, pulmonary haemorrhage due to antibodies targeting the α3(IV) collagen NC1 domain in glomerular and alveolar basement membranes. At Southern Medical Supplies Limited (SMSL), we support fast, definitive diagnosis with anti-GBM IgG testing (quantitative ELISA with optional immunoblot/IFA confirmation), kidney biopsy reagents demonstrating linear IgG (±C3) along the GBM by IF/IHC, and comprehensive rule-out/overlap panels including ANCA (for anti-GBM/ANCA dual-positivity), complements (C3/C4), infectious hepatitis/HIV screens, and renal injury profiling (creatinine/eGFR, ACR/PCR, urinalysis). Our solutions span ELISA, chemiluminescent immunoassay, immunoblot, immunofluorescence, immunohistochemistry, molecular, and clinical chemistry platforms sourced from a broad network of trusted global partners—EUROIMMUN, Ansh Labs, Randox, Streck, Bio-Rad, Abbott, Roche, Siemens Healthineers, Qiagen, bioMérieux, Cepheid, Werfen, Globe Scientific, ELGA LabWater, LW Scientific, Sebia, LTA SRL, Acrobiotech, MAKOL Innovacion Medica, Rayto Life and Analytical Sciences, Diazyme, Hardy’s Diagnostics, and Teco Diagnostics—delivering the analytical sensitivity, specificity, and reproducibility clinicians need for rapid confirmation and monitoring of anti-GBM disease.
