Parathyroid hormone, or PTH, is a peptide secreted by the parathyroid glands that serves as the principal regulator of calcium balance. Because PTH acts directly on bone, kidney, and intestine, its concentration in blood offers a sensitive window into how the body manages calcium and phosphate. A PTH test is therefore ordered whenever a clinician needs to distinguish among the several conditions that can disturb mineral homeostasis.

About Parathyroid Hormone (PTH) Test | Lab Test in Windsor

The PTH blood test quantifies the amount of parathyroid hormone circulating in the bloodstream.

PTH is released in response to falling ionized calcium levels, and it restores calcium by stimulating bone resorption, increasing renal calcium reabsorption, and promoting activation of vitamin D. When this feedback loop is disrupted, PTH may rise or fall in ways that point to a specific diagnosis.

Measurement is typically paired with a simultaneous serum calcium result, because the relationship between the two values carries more diagnostic weight than either number alone. A high PTH with high calcium suggests overactive parathyroid tissue, while a high PTH with low calcium points toward an appropriate compensatory response.

Results are interpreted alongside phosphate, vitamin D, magnesium, and kidney function, since each of these factors influences parathyroid activity. Clinicians use the pattern of these values, not the PTH level in isolation, to reach a conclusion.
