The diagnosis of hypoparathyroidism was made 8 years prior to her referral to us on the basis of low serum calcium (Ca=5.6 mg/dl), high serum phosphorus (Ph=9.6 mg/dl), and low intact parathyroid hormone levels (PTH=5 pg/ml), for which she has taken Calcitriol and calcium carbonate to maintain calcium and phosphorus hemostasis. Here, PTH is linked to hypoparathyroidism.
