ALB and hyperparathyroidism: Normocalcemic hyperparathyroidism was first acknowledged to be part of the diagnostic spectrum of PHPT during the Third International Workshop on the Management of Asymptomatic Primary Hyperparathyroidism in 2008,(1) and further defined and characterized at the Fourth International Workshop that followed in in 2014.(5) NHPT is characterized by persistently increased serum PTH levels in the setting of normal albumin‐adjusted and ionized serum Ca, after secondary causes of PTH elevation have been excluded.
