Is there anything else I need to know about a calcitonin test?If you are or have been treated for medullary thyroid cancer, you will probably be tested regularly to see if treatment was successful.You may also get regular calcitonin tests if you have a family history of multiple endocrine neoplasia type 2. Testing can help find C-cell hyperplasia or medullary thyroid cancer as early as possible. When cancer is found early, it's easier to treat.
