Overview

The intact PTH (Parathyroid Hormone) test measures the level of active parathyroid hormone in the blood, which helps regulate calcium levels.

1. High PTH Levels

• Often indicate hyperparathyroidism, which can cause elevated calcium levels and bone problems.

• Can also be seen in kidney disease or vitamin D deficiency.

2. Low PTH Levels

• May suggest hypoparathyroidism, leading to low calcium levels, muscle cramps, or spasms.

 

Used to diagnose and manage disorders related to calcium metabolism.

Test result interpretation

Interpretation

  1. High PTH with High Calcium:

    • Primary hyperparathyroidism (e.g., parathyroid adenoma)
  2. High PTH with Low Calcium:

    • Secondary hyperparathyroidism (e.g., vitamin D deficiency, chronic kidney disease)
  3. Low PTH with High Calcium:

    • Hypercalcemia of malignancy or excess calcium intake
  4. Low PTH with Low Calcium:

    • Hypoparathyroidism (e.g., autoimmune or post-surgical).
