Although initially, is recommended to measure TSH and, depending of results, FT4 and FT3, the measure of these, should be performed if pituitary disease, hyper-or hypothyroidism is suspected. The presence of autoantibodies reflects the presence of autoimmune disease, serum thyroglobulin is the best marker of differentiated thyroid carcinoma and calcitonin of medullary carcinoma.
