What is Parathyroid hormone (PTH)?
A parathyroid hormone (PTH) claret analysis measures the akin of parathyroid hormone in the blood. This analysis is acclimated to advice analyze hyperparathyroidism, to acquisition the could could could cause of aberrant calcium levels, or to analysis the cachet of abiding branch disease. PTH controls calcium and phosphorus levels in the blood.
PTH is fabricated by the parathyroid glands camera.gif, which are four pea-sized glands that lie abaft the thyroid gland camera.gif. If the claret calcium akin is too low, the parathyroid glands absolution added PTH. This causes the basic to absolution added calcium into the claret and reduces the bulk of calcium appear by the kidneys into the urine. Also, vitamin D is adapted to a added alive form, causing the belly to blot added calcium and phosphorus. If the calcium akin is too high, the parathyroid glands absolution beneath PTH, and the accomplished action is reversed.
PTH levels that are too top or too low can could could could cause problems with the kidneys and basic and could could could cause changes in calcium and vitamin D levels.
Tests for calcium and phosphorus levels in the claret may be done at the aforementioned time as a PTH test.
