Sarcoidosis is a multisystem granulomatous disease that demands a careful exclusion of mimics and objective biomarkers to track activity. At Southern Medical Supplies Limited (SMSL), we support the diagnostic work-up and monitoring of sarcoidosis with assays for serum ACE, soluble IL-2 receptor (sIL-2R), lysozyme, chitotriosidase, calcium/ionized calcium, and 1,25-dihydroxy vitamin D, alongside inflammatory markers (CRP/ESR) and rule-out testing such as TB molecular/IGRA and relevant fungal serologies. Our portfolio spans ELISA, chemiluminescent immunoassay, molecular PCR, microbiology, and clinical chemistry solutions sourced from our broad network of 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 sensitivity, specificity, and reproducibility clinicians need to confirm diagnosis, stage disease, and monitor treatment response in sarcoidosis.
