In simple words: A parathyroid hormone test checks the level of PTH in your blood. This helps doctors understand how your parathyroid glands are working and how your body is managing calcium levels.

This test measures the level of parathyroid hormone (PTH) in the blood. It is used to evaluate parathyroid gland function and calcium regulation.

Example 1: A patient with elevated calcium levels and suspected hyperparathyroidism undergoes PTH testing to confirm the diagnosis., A patient with low calcium levels and suspected hypoparathyroidism undergoes PTH testing to help determine the cause., A patient with chronic kidney disease undergoes regular PTH testing to monitor for secondary hyperparathyroidism, a common complication.

The documentation should include the reason for the PTH test, such as signs, symptoms, or related diagnoses (e.g., abnormal calcium levels, kidney disease).
