Calcitonin is the antagonist of parathyroid hormone in the regulation of calcium metabolism. Its production in the parathyroid glands and secretion of calcitonin is stimulated by an elevated calcium level and results in a reduction in the calcium concentration in the blood. Calcitonin inhibits osteoclast activity, and too low calcitonin levels are associated with oseopenia, a preliminary stage of osteoporosis. For this reason calcitonin is one of the substances given in osteoporosis therapy.

Calcitonin serodiagnostics is employed for clarification of scintigraphically cold thyroid nodules and for post-operative monitoring after removal of C-cell carcinoma. The serum calcitonin level is strongly increased in medullary thyroid carcinoma (C-cell carcinoma).

The quantitative determination of calcitonin in serum with the Calcitonin ELISA can be fully automated.
