Testing Parathyroid hormone (PTH) is used for a number of reasons which include, determining the cause of calcium imbalances, evaluating parathyroid function, diagnosing and differentiating between primary, secondary, and tertiary hyperparathyroidism, diagnosing hypoparathyroidism, during surgery for hyperparathyroidism, and confirming reomoval of the glands causing the problem., 
- The PTH test measures the amount of parathyroid hormone (PTH) in the blood.
- PTH functions is helping the body maintain stable levels of calcium in the blood
- No preparation is required.
High levels indicate:
- Parathyroid tumor
- Kidney disease and/or failure
Low levels indicate:
- Automimmune disorder
- Parathyroid damage or removal during surgery
- Genetic condition
- Severe illness
