Parathyroid Hormone Blood Test

£149

Worried about calcium imbalances or bone health? Parathyroid hormone (PTH) plays a key role in regulating calcium, phosphate, and vitamin D levels, which are essential for strong bones and muscle function. This test helps assess for parathyroid gland dysfunction, which can contribute to a calcium imbalance, osteoporosis, kidney stones, or unexplained muscle weakness.

You'll need to visit The Doctors Laboratory in London to collect your sample as the sample is not suitable for posting.

Parathyroid hormone (PTH) is important in controlling blood calcium levels. When calcium levels are low, the parathyroid gland releases PTH into the bloodstream. PTH is able to retrieve calcium from bone, stimulate vitamin D activation in the kidneys and suppress calcium excretion in the urine.

FAQs

What happens if parathyroid hormone levels are high or low?

Too high or too low parathyroid hormone levels can affect bone and kidney health and vitamin D levels.

What does the parathyroid hormone do?

Parathyroid hormone regulates calcium levels by mobilising calcium into the blood from bone, enhancing the absorption of calcium from the small intestine and controlling the amount of calcium lost in the urine. Our test identifies any overactivity in the glands producing parathyroid hormone while helping to find the cause of abnormal blood calcium levels.

What is the parathyroid hormone?

The parathyroid hormone (PTH) is produced by a cluster of four small tiny glands which lie directly behind the thyroid glands. PTH regulates calcium levels in the blood, helping to increase levels when they are too low.
