For recurrent kidney stones, parathyroid hormone (PTH) levels should be checked. PTH regulates calcium balance and abnormalities in its levels could contribute to stone formation. Assessing PTH can help identify conditions like hyperparathyroidism.
When investigating recurrent kidney stones, the hormone to check for normal levels is parathyroid hormone (PTH). PTH plays a key role in regulating calcium balance by stimulating the conversion of calcidiol to active vitamin D, which increases calcium absorption. It also decreases phosphate reabsorption in the kidneys, preventing phosphate from binding to calcium in the blood, which can lead to stone formation.
In cases of hyperparathyroidism, excessive secretion of PTH can result in elevated blood calcium levels, which is a contributing factor to kidney stone formation.
PTH levels should be assessed to ensure they are within normal range to help determine the cause of recurrent kidney stones. Abnormal PTH levels might indicate an underlying condition, such as hyperparathyroidism, that could be causing the stones.
