PTH Blood Test - More Information

The PTH test, also known as a parathyroid hormone test, measures the blood level of intact PTH and the calcium level.

PTH is a hormone made by the parathyroid gland and is used to help evaluate parathyroid function. The parathyroid glands sit on the edges of the thyroid gland but, in spite of their name, are not involved with producing any thyroid hormones. Frequently, the PTH level is checked because one's calcium blood level is abnormally high or low and, as a primary regulator of calcium, the PTH blood level becomes important.

The relationship between the PTH blood level and calcium helps with the evaluation of the parathyroid gland. Hyperparathyroidism is when the PTH test level is found to be abnormally high. Hypoparathyroidism is when the PTH is found to be abnormally low. People who have had parathyroid surgery or are on dialysis for end-stage kidney disease also need to have their PTH test levels measured on a consistent basis.

As can be seen on the sample PTH lab report above, your PTH test report will show your PTH intact and calcium blood levels as numerical results. Based on how your blood levels compare against the lab's reference ranges, an interpretation can be made as to whether the parathyroid gland is functioning normally or you have hyperparathyroidism or hypoparathyroidism.
