Understanding the test
What does the Thyroglobulin (TG) test measure?
Also called Thyroid Cancer Marker
Thyroglobulin can help monitor selected patients after treatment for differentiated thyroid cancer. The type of surgery, remaining thyroid tissue and prior results matter.
When it may be requested
Following selected thyroid cancers
A specialist may monitor thyroglobulin after treatment for differentiated thyroid cancer.
Checking antibody interference
Thyroglobulin antibodies can change the reliability of the measurement.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
Follow your specialist's instructions about timing after thyroid treatment and in relation to thyroid medicines. Report biotin and ask whether anti-thyroglobulin antibodies will be assessed with the same draw.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
A change in thyroglobulin must be interpreted with antibody status. A result from someone with an intact thyroid differs in meaning from a post-treatment monitoring result.
What can affect it
- Thyroglobulin is also made by normal thyroid tissue and is not a screening test for thyroid cancer.

Patient questions
Before you book
Why check anti-thyroglobulin antibodies alongside it?
These antibodies can interfere with some measurement methods. Your specialist needs that information and the details of your previous thyroid treatment.
Do I change my thyroid tablets before collection?
Follow the specific plan from your treating specialist. Some monitoring protocols use a particular TSH condition. Do not change a prescribed thyroid medicine on your own.
What does a rise after thyroid cancer treatment mean?
The trend needs specialist review alongside surgery history, TSH, antibodies, earlier results and imaging. A single increase does not confirm recurrence.
