Value of Repeat Stimulated Thyroglobulin Testing in Patients with Differentiated Thyroid Carcinoma Considered to Be Free of Disease in the First Year After Ablation

Abstract

The present results favor repeating stimulated Tg 5 years after ablation in patients who were initially considered to be free of disease and who continued to have Tg/T4 values of <1 ng/mL and negative TgAb tests. A negative predictive value of 100% was obtained for patients who continued to have low stimulated Tg values.
