Investigating patients with normocalcemic hyperparathyroidism: When is a parathyroid scintigraphy indicated?

Author information

Department of Internal Medicine, Naval Hospital of Crete, Chania, Greece.


In clinical practice, physicians often encounter patients with persistent elevated serum parathyroid hormone levels and normal serum calcium levels, a state known as normocalcemic hyperparathyroidism (NHPT). The investigation of NHPT cases can lead to unnecessary use of parathyroid scintigraphy (PS) and consequently unnecessary health-care costs. In this clinical review, the most common causes of NHPT and the possible indications for PS performance in such cases are mainly presented and discussed.
