Test ID: HTGFN    
Thyroglobulin, Tumor Marker, Fine-Needle Aspiration (FNA)-Needle Wash, Lymph Node

Useful For Suggests clinical disorders or settings where the test may be helpful

An adjunct to cytologic examination of fine-needle aspiration specimens in athyrotic individuals treated for differentiated thyroid cancer, to confirm or exclude metastases in enlarged or ultrasonographically suspicious lymph nodes


This test is not useful for screening asymptomatic individuals for neoplastic disease.


Detection of thyroglobulin in fine-needle aspiration (FNA)-needle washes improves the evaluation of suspicious lymph nodes in patients with differentiated thyroid carcinoma.


Measurement of thyroglobulin is particularly useful in cases where the cytology result is nondiagnostic or indeterminate.


In athyrotic patients with a history of differentiated thyroid carcinoma, a FNA thyroglobulin value greater than 1 ng/mL suggests the presence of metastatic differentiated follicular cell-derived thyroid carcinoma.
