文摘

BackgroundThe diagnosis of primary hyperparathyroidism (1°HP) has become more complex, as fewer patients present with classic phenotype of concomitant elevation of calcium and parathyroid hormone (PTH). In addition, the distinction between normal versus abnormal patients is challenging, with an increasing number of patients with 1°HP, who have calcium and/or PTH values within the “reference” range. Patients with “inappropriately” elevated PTH values relative to their serum calcium are considered to have 1°HP.
