Parathyroid Hormone (PTH)
Item Catalog Number: LC015610
Parathyroid hormone (PTH) is secreted by the parathyroid glands and acts to increase the concentration of calcium (Ca2+) in the blood. PTH acts upon parathyroid hormone receptors in three parts of the body:
- Bone — takes calcium out of the bones, making bones less dense.
- Kidneys — puts calcium back into the blood from urine.
- Intestines — increases calcium absorption from the gut.
The parathyroid hormone blood test is used in detecting parathyroid disease, detecting and monitoring other diseases of calcium homeostasis and is used for monitoring individuals undergoing renal dialysis.
You can check your parathyroid hormone blood level with or without fasting. Take all medications as prescribed. Do not take supplements the day of the test. This test is not included in any other panel offered by Life Extension®.
