Is Thyroid peroxidase antibody level the same as Thyroglobulin for blood test purposes?

Hi everyone, I've just had some blood tests back from my GP surgery for my endo apptmt - my endo requested FT3, FT4, TSH, Thryoglobulin and anti-thyroglobulin to be tested. My blood test results have come back and they've tested FT3, FT4, TSH and 'Thyroid peroxidase antibody level'. The Dr's surgery has told me that this is what the lab tests now and it's the same as the thyroglobulin. Does anyone know if this is the case please?

This doctor has a series of hidden causes of low thyroid and this 5-minute video is about thyroglobulin.

It is difficult to be sure what answer you need.

Most people with auto-immune thyroid disease (Hashimoto's) will have antibodies to Thyroid Peroxidase (TPOab) AND antibodies to Thyroglobulin (TGab).

More people will have TPOab than TGab - but a few people might be positive on TPOab, yet negative on TGab.

Generally, TPOab seems to be the preferred test. Few people are tested for both.

However, there is ALSO a Thyroglobulin test

The thyroglobulin test is primarily used as a tumour marker to determine the effectiveness of thyroid cancer treatment and to monitor for recurrence.

That site has summary information about a vast range of blood tests.
