Hashimoto's antibodies - blood tests

Hi everyone,

My doctor finally agreed to test my blood for thyroid antibodies, but I am suddenly concerned that he hasn't put the correct ones on the request form. He has written:

"Thyroid Function Tests (TFT) (TFT)

Thyroid Peroxidase Antibody (TPO) (TPO)

THYROID RECEPTOR ABS (TRAB)"

I am particularly concerned that the last one is not right. But perhaps it is?

Any help would be appreciated.

Best Wishess

To test for Hashimoto's it's usually TPO and TG antibodies

TRab is to test for Graves' disease

Thank you so much SlowDragon for your fast reply.

I had seen on the forum that the last item on my list of antibodies to be tested relates to Graves' Disease. Does this mean that it is an irrelevant test when one has been diagnosed with hypothyroidism?

Do I need to get the request form changed to Include the test for TG antibodies or is it sufficient as it stands for diagnosis of Hashimoto's?

Thank you very much for the very interesting links.

If TPO antibodies are high then lab should test TG antibodies

If TPO are low, lab unlikely to test TG antibodies even if GP had requested
