Thyroglobulin, Tumor Marker, Fine-Needle Aspiration (FNA)-Needle Wash, Lymph Node
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
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.
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
