* This is not a home test kit. You will need to visit a local lab for testing.


The calcitonin test is primarily used to help diagnose C-cell hyperplasia and medullary thyroid cancer (MTC), to evaluate the effectiveness of treatment for MTC, and to monitor patients for recurrence of MTC following treatment. It is also used to screen for MTC in family members of patients with MEN 2
