Elevated PTH and blood calcium levels were first identified in May 2021 at the Endocrinology Research Centre: PTH level – 21.5 pmol/L (up to 6.9 pmol/L), hypercalcemia – 3.2 mmol/L (2.1-2.55 mmol/L), and normophosphatemia – 0.8 mmol/L (0.74-1.52 mmol/L). This evidence concerns the gene PTH and Hypercalcemia.
