SERUM THYROGLOBULIN CONCENTRATIONS AND (131)I WHOLE-BODY SCAN RESULTS IN PATIENTS WITH DIFFERENTIATED THYROID CARCINOMA AFTER ADMINISTRATION OF RECOMBINANT HUMAN THYROID-STIMULATING HORMONE
Our results show that the measurement of serum Tg concentrations after rhTSH has a higher diagnostic value than whole-body scanning in detecting the persistence of thyroid tissue. Therefore, rhTSH should be administered in TSH-suppressed patients with basal serum Tg concentrations of <2 ng/mL because the increment in serum Tg concentrations may reveal the persistence of thyroid tissue in these patients
