Uromodulin (Tamm–Horsfall protein) is the most abundant kidney-derived urinary protein and a sensitive biomarker of tubular integrity and nephron mass—with reduced urinary/serum levels linked to chronic kidney disease risk, hypertensive nephrosclerosis, and recovery after AKI, and optional UMOD genotyping relevant in familial uromodulin-associated kidney disease. At Southern Medical Supplies Limited (SMSL), we provide urine and serum uromodulin assays (ELISA/chemiluminescent immunoassay) with reflex UMOD molecular testing where indicated, plus compatible collection and pre-analytical supplies to protect sample stability. Our portfolio draws on an expanded network of 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, reproducibility, and workflow support clinicians need to stratify risk, guide therapy, and monitor renal outcomes with confidence.
