Explanation:
Detailed explanation-1: -Serum phosphate levels are high in primary and secondary hyperparathyroidism and low in primary hyperparathyroidism due to increased renal phosphate excretion.
Detailed explanation-2: -Because factors that cause parathyroid hyperplasia, such as lower calcium intake, increase the probability that a parathyroid cell will undergo a somatic mutation and subsequent clonal proliferation, such factors could increase the risk for developing primary hyperparathyroidism.
