Adrenal function disorders—including adrenal insufficiency (primary/secondary), Cushing’s syndrome, primary aldosteronism, congenital adrenal hyperplasia (CAH), and pheochromocytoma/paraganglioma—require integrated assessment of the HPA axis and adrenal cortex/medulla. At Southern Medical Supplies Limited (SMSL), we offer comprehensive panels covering basal and dynamic evaluation: serum/salivary/urinary cortisol, ACTH, 1-mg overnight dexamethasone suppression, cosyntropin (Synacthen) stimulation support, 17-hydroxyprogesterone and extended steroid profiles for CAH, DHEA-S, aldosterone, direct renin/PRA with ARR, plasma free and urinary fractionated metanephrines/catecholamines, plus electrolytes and acid–base status, with targeted molecular assays where indicated. Our portfolio spans ELISA, chemiluminescent immunoassay, molecular, and clinical chemistry platforms 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 analytical sensitivity, specificity, and reproducibility clinicians need to confirm etiology, guide therapy, and monitor outcomes in adrenal disease.
