The Parathyroid Hormone (PTH) test measures the level of parathyroid hormone in the blood. PTH is produced by the parathyroid glands and plays a crucial role in regulating calcium levels in the body. This test is used to diagnose and monitor conditions related to calcium metabolism, parathyroid gland function, and bone health. It's particularly useful in evaluating hyperparathyroidism, hypoparathyroidism, vitamin D deficiency, and kidney disorders that affect calcium balance. The test is often ordered alongside calcium and vitamin D tests to provide a comprehensive picture of calcium homeostasis. Abnormal PTH levels can indicate various disorders, including parathyroid tumors, chronic kidney disease, or problems with calcium absorption.
A low PTH level (below 15 pg/mL) may indicate:
Low PTH can lead to hypocalcemia (low blood calcium), which may cause muscle cramps, tingling sensations, and in severe cases, seizures or heart rhythm abnormalities. Further testing and medical evaluation are necessary to determine the underlying cause and appropriate treatment.
A high PTH level (above 65 pg/mL) may indicate:
Elevated PTH can lead to hypercalcemia (high blood calcium), which may cause fatigue, weakness, kidney stones, bone pain, and cognitive symptoms. Chronic high PTH can result in osteoporosis and increased fracture risk. Further evaluation is needed to identify the cause and determine appropriate management.
