Overview
The diagnosis of hypoparathyroidism is made when the following diagnostic 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.
Diagnostic Criteria
- The diagnosis of hypoparathyroidism is made when the following diagnostic criteria are met:[1][2]
- 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).
- After neck surgery, chronic hypoparathyroidism is established only after 6 months.
