Thyroglobulin Blood Test

Thyroglobulin is a protein produced in the thyroid. The Thyroglobulin Blood Test measures the level of this protein in your blood. This protein is not normally found in the bloodstream, so its presence indicates that there is a problem with the thyroid. This test can be used to help diagnose autoimmune conditions that affect the thyroid.


Why test for thyroglobulin?

Common reasons for this blood test are:

  • To investigate symptoms that could indicate a problem with your thyroid
  • To get a clear picture of your thyroid function and health
  • Monitor thyroid function over time.

Frequently Asked Questions

No, we will send you the results and recommend that you share these with your GP or fertility provider.

It is not unusual for some bleeding to occur under the skin following your blood test and sometimes this can extend a little further around the puncture site.  If this causes you concern, check with your practice nurse. 

Sometimes we cannot get a blood sample from you. This can be for many reasons, such as not being hydrated enough, feeling cold or having another blood test recently. We will always offer you another appointment so we can try again.
