Thyroglobulin, Tumor Marker, Fine-Needle Aspiration Biopsy Needle Wash

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

Confirming or excluding metastases in enlarged or ultrasonographically suspicious lymph nodes from athyrotic individuals treated for differentiated thyroid cancer in conjunction with cytologic analysis

 

Confirming or excluding the presence of thyroid tissue in the biopsied area from athyrotic individuals treated for differentiated thyroid cancer in conjunction with cytologic analysis

 

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

Highlights

-Measurement of thyroglobulin in fine-needle aspiration biopsy (FNAB) needle washes improves the evaluation of suspicious lymph nodes in athyrotic patients suspected of metastatic differentiated follicular cell-derived thyroid carcinoma.

-Measurement of thyroglobulin is particularly useful in cases where the cytology result is not diagnostic or indeterminate.

-Interpretation of thyroglobulin concentrations in FNAB-needle washes from tissues other than lymph nodes is less well defined.
