Notably, she had primary hyperparathyroidism (parathyroid hormone [PTH] 16.8 pmol/L [158.5 pg/mL], reference 1.6-6.9 pmol/L; [15.1-87.7 pg/mL]) and mild hypercalcemia (albumin-corrected calcium 2.76 mmol/L [11.06 mg/dL], reference 2.10-2.60 mmol/L; [8.4-9.5 mg/dL]). Here, PTH is linked to hypercalcemia disease.
