Lymphocytic Thyroiditis on Histology Correlates with Serum Thyroglobulin Autoantibodies in Patients with Papillary Thyroid Carcinoma: Impact on Detection of Serum Thyroglobulin

Abstract

In papillary thyroid carcinoma, LT on histology must be carefully searched for because it is frequently associated with TgAb and therefore mistakenly low or undetectable Tg. TgAb can be missed by some assays. In absence of LT, TgAb are rare.
