Bechterew’s disease (Ankylosing spondylitis) is a seronegative spondyloarthritis marked by axial back pain, sacroiliitis, and extra-articular features. At Southern Medical Supplies Limited (SMSL), we support diagnosis and monitoring with HLA-B27 genotyping, inflammatory markers (CRP, ESR), fecal calprotectin when IBD overlap is suspected, and rule-out panels (e.g., RF/anti-CCP to exclude RA), plus baseline labs for biologic eligibility and safety. Our solutions span molecular, ELISA/chemiluminescent immunoassay, and clinical chemistry platforms sourced from our expanded partner network—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 sensitivity, specificity, and reproducibility for confident AS care.
