Serum Thyroglobulin, High-Resolution Ultrasound, and Lymph Node Thyroglobulin in Diagnosis of Differentiated Thyroid Carcinoma Nodal Metastases

Abstract

Nodal FNAB needle-wash Tg measurements complement cytology in thyroid cancer follow-up and might substitute for it. The combination of unremarkable ultrasonography and an undetectable serum Tg in Tg autoantibody-negative patients might obviate the need for FNAB.
