In patients with hypoparathyroidism it is recommended to perform clinical monitoring (assessment of hypo/hypercalcemia symptoms) as well as monitoring of calcium levels corrected for albumin, phosphorus and magnesium levels, creatinine and estimated glomerular filtrate value every 3–6 months, 24-h urine calcium and creatinine level test once a year if the patient is stable. The gene discussed is ALB; the disease is hypoparathyroidism.
