Parathyroid Hormone (PTH)

Testing for Parathyroid Hormone (PTH) is primarily used to determine the cause of abnormal calcium levels and to monitor chronic kidney disease or hyperparathyroidism. Because PTH works in a tight feedback loop with calcium to maintain bone health and nerve function, this test is essential for pinpointing whether a chemical imbalance stems from the parathyroid glands themselves or an underlying issue like Vitamin D deficiency. By measuring PTH, clinicians can distinguish between different types of bone metabolism disorders, evaluate the risk of kidney stones, and ensure that the thermostat for your body mineral balance is functioning correctly.
