Scientific name: Thyroglobulin Antigen Test
A quantitative test to measure the concentration of thyroglobulin (Tg) protein in blood serum. This protein is produced exclusively by the follicular cells of the thyroid gland. After total thyroidectomy and radioactive isotope therapy, its level should become undetectable; an elevated level thereafter is a sign of disease recurrence.

Medical Service Information
Conditions & Notices
- Routine fasting is not required, but the treating physician's instructions must be followed precisely, especially regarding the timing of taking the thyroid hormone replacement dose.
- Thyroglobulin antibodies (TgAb) should be routinely measured in the same sample to avoid false results.
- The timing of the test is very important for follow-up. The doctor may order the test with a high (stimulating) or low (suppressive) TSH level, depending on the follow-up protocol.
- The laboratory and the doctor must be informed of any previous radioactive iodine treatment or surgical procedures.
