PTH (Parathyroid Hormone)
Parathyroid hormone is secreted by the parathyroid glands in response to low serum calcium and raises calcium by mobilizing bone, increasing kidney reabsorption, and activating vitamin D. Elevated PTH occurs in primary hyperparathyroidism and secondary forms from kidney disease or vitamin D deficiency and can drive bone loss. Low PTH suggests hypoparathyroidism.
