About Our Parathyroid Hormone (PTH) Test
Note: Fasting is not required for this test.
This blood test is used to diagnosis parathyroid disease and other diseases that involve calcium homeostasis. This test can also be used to monitor patients undergoing renal dialysis.
Parathyroid hormone (PTH) is a protein hormone secreted by the parathyroid glands that controls the blood's calcium, vitamin D and phosphorus levels. PTH plays a key role in bone growth.
