Quick answer
The Parathyroid Hormone test measures the level of PTH in the blood. PTH is released by the parathyroid glands and is the main regulator of calcium balance in the body. The test is usually interpreted alongside a calcium measurement, because together they help show whether the parathyroid glands are responding appropriately.
What this test measures
The parathyroid glands sit near the thyroid in the neck and release PTH in response to low blood calcium. PTH raises calcium by acting on bone, the kidneys, and the gut. Because calcium and PTH work in a tight feedback loop, measuring PTH alone can be misleading, so clinicians typically review it with calcium and sometimes vitamin D or phosphate.
Testing may be ordered when a routine blood test shows abnormal calcium, or when someone has symptoms that could relate to parathyroid function, such as bone discomfort, kidney stones, or fatigue. It can also be used to follow a known parathyroid condition or to investigate an unclear calcium problem.
Interpretation depends on context. A high PTH with a high calcium points in one direction, while a high PTH with a low calcium points in another. Results can be influenced by vitamin D status, kidney function, and medications, so a qualified healthcare provider evaluates the whole picture before drawing conclusions.
