What this test is
The parathyroid hormone test is a blood test that quantifies the amount of PTH, a hormone produced by the parathyroid glands. PTH regulates calcium and phosphorus levels in the body. This test is often used alongside calcium tests to assess parathyroid disorders.
What it measures
- Parathyroid hormone (PTH) — reflects parathyroid gland activity and its effect on calcium regulation
- Calcium — often measured alongside PTH to assess calcium balance
- Phosphorus — sometimes included to evaluate mineral metabolism
- Albumin — may be used to correct total calcium levels
- Vitamin D — can be checked to rule out vitamin D deficiency as a cause of abnormal PTH
What the test involves
The test requires a standard blood draw, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order a PTH test to investigate abnormal calcium levels or to help diagnose parathyroid conditions. It can also be used to monitor certain metabolic bone diseases or during treatment for parathyroid disorders.
Preparation
Preparation instructions vary by laboratory, so follow the specific directions provided by your collection lab. Some labs may require fasting or timing the test to a certain part of the day.
How results are reported
