Parathyroid health blood tests measure hormones and minerals that regulate calcium and bone metabolism. The parathyroid glands control levels of parathyroid hormone (PTH), calcium, phosphate, and vitamin D, which are essential for strong bones, muscle function, and nerve health. Abnormal results may indicate conditions such as hyperparathyroidism, hypoparathyroidism, osteoporosis, or chronic kidney disease. Our parathyroid health panels provide valuable insights to support bone strength, mineral balance, and overall endocrine health.
