Laboratory

Calcitonin [Moles/volume] in Serum or Plasma --1 minute post XXX challenge

Definition

Calcitonin is a sensitive tumor marker of medullary thyroid carcinoma (MTC). Patients with MTC have usually very high levels of serum calcitonin that can be used to diagnose the disease. To improve diagnostic sensitivity in family members with small MTCs, or to evaluate postoperative biochemical cure status, measurement of calcitonin stimulated with combined intravenous calcium gluconate and pentagastrin (calcitonin challenge) has been widely adopted.
