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.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for PTH (Parathyroid Hormone). How we verify ranges.
- No stated targetNo separate optimal establishedInterpret with calcium and vitamin D; PTH rises when vitamin D is low
- Lab reference interval15-65 pg/mLWhat a lab report flags against. A lab interval is not an optimal target.
