Report: Contact us to know the TAT.
Usage: Residual or recurrent Medullary thyroid carcinoma (MTC) after thyroidectomy is diagnosed by elevated serum Calcitonin levels. In minimal residual MTC or C-cell hyperplasia where imaging studies are negative and, basal Calcitonin levels are often normal, stimulation tests are required. This is a sensitive test for early diagnosis of subclinical hypercalcitoninemia in patients with minimal MTC.
