Indication
Calcitonin determination is used as an aid in the diagnosis and treatment of diseases involving the thyroid and parathyroid
glands, including carcinoma and hyperparathyroidism in conjunction with other clinical and laboratory findings. The most
prominent clinical syndrome associated with a disordered hypersection of hCT is the medullary thyroid carcinoma (MTC),
which comprises 5
– 10
% of all thyroid cancers. It may occur sporadically or in a familial form that is inherited as an auto‑
somal dominant trait. Furthermore, calcitonin
measurements can also be used to monitor the efficacy of therapy in patients
with calcitonin producing tumors
