Chemiluminescence Immunoassay (immunoenzymatic)
Useful to assess presence of residual papillary-follicular carcinoma, thyroid, following resection
Thyroglobulin: 0.0 - 35.0 ng/mL; Thyroglobulin Antibody: 0 - 3 IU/mL.
Not valid for medullary carcinoma of thyroid. High values of thyroglobulin are found in nodular goiter and normal levels are found in patients with small thyroid carcinomas. Therefore, this is not a screening test for thyroid cancer. There is interference in serums containing autoantibodies.

- Thyroid Antibody and Thyroglobulin
- Antithyroglobulin Antibody and Thyroglobulin
Collect specimen in SST tube. Centrifuge, aliquot serum into a plastic vial and freeze.
Thyroglobulin is not the same as thyroxine-binding globulin. It is a prohormone made by thyroid follicular cells.
