Laboratory evaluation of anatomic disorders of the thyroid.
Thyroid function tests, radioiodine uptake and scintiscanning, and antithyroid antibody titers are the main laboratory tests useful in the management of goiter. Scintiscanning and ultrasonography aid in differentiating a functioning adenoma from a "cold" solid nodule--a crucial distinction since the incidence of cancer in a cold nodule is 20 percent. Radioiodine scanning and serum thyroglobulin help in the diagnosis of a well-differentiated thyroid cancer. Serum calcitonin serves as a reliable tumor marker for medullary carcinoma.
