In patients with permanent hypoparathyroidism, in addition to an analysis of the free-ionized or albumin-adjusted calcium concentrations every 3–6 months, the ESE recommended monitoring of phosphate/the calcium-phosphate product, magnesium and the renal function (including 24-h urinary calcium and creatinine excretion in intervals from 6 to 12 months) [12]. The gene discussed is ALB; the disease is hypoparathyroidism.
