We believe our study will lead to further study in posttransplant hypercalcaemic patients to evaluate and compare posttransplant PTH levels between the normocalcaemic and hypercalcaemic group, which will help determining postrenal transplant recommended PTH level and will guide us regarding the management of posttransplantation hyperparathyroidism leading to hypercalcaemia. This evidence concerns the gene PTH and Hypercalcemia.
