Ultrasound-guided FNA biopsies from each lymph node were subjected to cytologic evaluation, and levels of thyroglobulin in the washout fluid were measured with a highly sensitive, monoclonal ...

Our initial diagnostic difficulty originated because of the coexistence of undetectable Tg (clearly incompatible with the degree of surgery) [6] with negative TgAb in a patient with several ...

Thyroglobulin (Tg) is thyroid but not tumor specific. Serum Tg levels less or equal to 0.1 ng/ml in patients without Tg autoantibodies (TgAbs) indicate cure following total thyroid ablation when ...
