The thoracic spine (upper back) has a normal outward curvature that is medically referred to as kyphosis or the kyphotic curve by which the spine is bent forward. In this discussion, the term kyphosis will be used to discuss abnormal kyphosis. The spine is normally straight when looking from the front.
A parathyroid hormone (PTH) blood test measures the level of parathyroid hormone in the blood. This test is used to help identify hyperparathyroidism, to find the cause of abnormal calcium levels, or to check the status of chronic kidney disease. PTH controls calcium and phosphorus levels in the blood.
Parathyroid Hormone (PTH), Intact. This test is used for diagnosis of parathyroid disease and other diseases of calcium homeostasis including monitoring patients undergoing renal dialysis.PTH is an 84 amino acid peptide hormone which is responsible for the regulation of serum calcium levels within a narrow range.PTH is secreted in response to decrease in serum calcium levels by increasing the renal reabsorption of calcium and lowering reabsorption of phosphorus.TH is an 84 amino acid peptide hormone which is responsible for the regulation of serum calcium levels within a narrow range.
