Disorders of calcium and bone metabolism—including hyperparathyroidism, hypoparathyroidism, osteomalacia, osteoporosis, and CKD–MBD—require integrated testing across mineral, hormonal, and bone‐turnover pathways. At Southern Medical Supplies Limited (SMSL), we provide comprehensive panels covering total and ionized calcium, phosphate, magnesium, albumin (for corrected calcium), intact PTH, 25-OH vitamin D (status) with reflex 1,25-(OH)₂D where indicated, alkaline phosphatase with bone-specific isoenzyme, bone turnover markers (P1NP, CTX, osteocalcin), calcitonin as appropriate, FGF23 for hypophosphatemic disorders, urine Ca/Cr ratio or 24-hour calcium/phosphate, and renal indices (creatinine/eGFR). When malabsorption is suspected, we can add celiac and autoimmune screens. Our portfolio spans clinical chemistry, ELISA, chemiluminescent immunoassay, and molecular platforms sourced from a broad network of trusted 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 accuracy, sensitivity, and reproducibility needed to identify etiology, guide vitamin D/calcium and antiresorptive or anabolic therapy, and monitor treatment response.
