The diagnosis of hypoparathyroidism is made when the following<unk>  criteria are met, hypocalcemia (albumin-adjusted) confirmed on at least two occasions separated by at least 2 weeks, parathyroid hormone (PTH) concentration, by second- or third-generation immunoassay, that is undetectable or inappropriately low (ie, <20 pg/mL) in the presence of hypocalcemia on at least two occasions, phosphate levels in the upper normal or frankly elevated range (helpful but not mandatory), and chronic hypoparathyroidism is established only after 6 months after neck surgery.
