Why do I still have Thyroglobulin Antibodies after my TT surgery?

[Justin1967]

Here is my latest Blood results ( pre RAI)

Tsh:  67 mU /l  (0.4-4.0)
FT4: <5.2 pmol/l  (9-19)
and  Urine Iodide was 20 ug/l (100-250)

Tg - serum is 3 ug/l
Comment- The presence of anti-thyroglobulin antibodies may cause
falsely low thyroglobulin results, includeing undetectable thyroiglobulin results

Thyroglobulin antibodies:  37 iu/ml (0-150)
Thyroid Peroxidase : 13 iu/ml (0-150)

Calcium 2.37 mmol (2.10- 2.60)
Albumin 47g/l  (38-52)
Calcium  2.23mmol/l (2.10-2.6)
Inorganic Phosphate 1.01 mmol ) (0.7- 1.50)

Does the thyroglobulin anitbodies result mean anything after RAI?

Your antibody levels are fairly low, which is good.

You will always produce antibodies. Removing the throid and having RAI does not repair your immune system.

Thyroid antibodies are produced by your immune system. Your immune system is not supposed to attack your organs. Your numbers are very low, though, so it should not affect your health in the future.

Almost everyone produces thyroid antibodies in very low numbers. Why that is, I do not know. If your numbers were quite high, then it would be a concern for future health. It could lead to your immune system creating other undesireable antibodies.

In your case, it looks like a minor concern, but you will always produce these antibodies to some extent. The numbers will likely go down now that you have irradicated the gland.

Hope you are on meds now and start feeling better soon.

What is the correlation between thyroglobulin & thyroglobulin antibodies?
Why do they say - The presence of anti-thyroglobulin antibodies may cause
falsely low thyroglobulin results, including undetectable thyroglobulin results?

Here is a link that addresses thyroglobulin and goes into great detail answering your questions.

You just had RAI very recently, didn't you?

[Justin1967]

Yes I have had RAI recently 9 days ago.. Thanks for the link, I will look into it..
