Parathyroid Hormone

About this test

Parathyroid hormone (PTH) is produced by a cluster of four tiny glands in the neck, directly behind the thyroid glands. Their role is to control phosphorus and calcium levels in the blood.

Levels of parathyroid hormone (PTH) that are either too high or too low can cause medical problems for the bones and the kidneys, as well as significant changes in the productions of calcium and vitamin D levels.

This test identifies any over activity in the glands producing parathyroid hormone (PTH), while finding the cause of any abnormal blood calcium levels.

Who is this test for?

This blood test is designed for people who wish to measure levels of parathyroid hormone (PTH) to identify over-activity in the glands next to the thyroid glands (hyperparathyroidism).
