Parathyroid Hormone

Parathormone, PTH (Parathyroid Hormone) Test

How To Prepare

Do not eat or drink anything except water for 8 to 10 hours before the test. A PTH test is usually done before 10 a.m. because PTH levels go up quickly after you wake up. However, your health professional will discuss any changes to this schedule with you. Tell your doctor if you work nights so that you can arrange to have your blood tested shortly after you wake up.

Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results may mean. To help you understand the importance of this test, fill out the medical test information form(What is a PDF document?).
