Why This Biomarker Matters

Elevated calcitonin, particularly high levels, suggests medullary thyroid cancer. Regular monitoring helps detect thyroid malignancy early, enabling timely treatment and improving outcomes.

Overview

Calcitonin is a hormone produced by the thyroid gland that regulates calcium and phosphate metabolism by promoting calcium excretion and bone formation. Blood calcitonin levels are primarily used to screen for and monitor medullary thyroid carcinoma (MTC), a rare thyroid cancer where calcitonin is markedly elevated. The test is also useful in assessing bone metabolism and osteoporosis risk. Elevated calcitonin, especially when very high, warrants investigation for thyroid cancer or other malignancies. Baseline calcitonin testing is recommended for people with family history of thyroid cancer or hereditary cancer syndromes.
