Parathyroid Scintigraphy


Parathyroid scintigraphy is a test used to look at parathyroid glands and tissues in your neck. The parathyroid glands maintain calcium and phosphate levels in your body. Sometimes the parathyroid glands are overactive. The test may show an adenoma (non-cancerous tumor) that is preventing the parathyroid glands from working properly. Parathyroid scintigraphy helps healthcare providers diagnose your condition and plan your treatment.


Follow up with your healthcare provider, surgeon, or endocrinologist as directed:

Write down your questions so you remember to ask them during your visits.


  • Drink liquids as directed. Ask how much liquid to drink each day and which liquids are best for you. Liquids will help flush the radioactive medicine out of your body.
  • You may not be able to breastfeed after this test. Ask how long you must stop breastfeeding.

Contact your healthcare provider, surgeon, or endocrinologist if:

  • You have learned that you are pregnant.
  • Your sense of taste changes after the test.
  • You develop a red, itchy rash, hives, or tingling in your mouth or throat.

Seek care immediately or call 911 if:

  • Your chest feels tight or you are having trouble breathing.
