The hypophosphatasia/hyperphosphatasia misdiagnosis (i.e., June 2023) can be easily rejected since the blood count and urine test displayed no such signs (i.e., high phosphate serum levels, low levels of parathyroid hormone due to hypercalcemia and hypercalciuria) [15,16,17,29,30]. Here, PTH is linked to Hypercalcemia.
