Biological tests showed corrected hypercalcemia at 3.07 mmol/L, phosphatemia at 0.93 mmol/L, calcemia/phosphoremia ratio is 3.3, elevated PTH at 2613 pg/mL, elevated alkaline phosphatase at 3669 IU, and a deficiency in 25‐hydroxyvitamin D3 at 7.1 ng/mL. Here, PTH is linked to hypercalcemia disease.
