Purpose: Calcitonin is the most sensitive tumor marker of medullary thyroid carcinoma (MTC) and a calcium stimulation test is used to improve this sensitivity. In Japan, the electrochemiluminescence immunoassay (ECLIA) is currently the only test performed to measure serum calcitonin. There is a gender difference in the reference value of serum calcitonin; however, a reference upper limit for use with ECLIA has been reported only for women, but not for men. Read More
