regarding levels of anti thyroglobulin

Hi,
Could anyone please tell me if they know how much the levels of thyroglobulin and anti thyrogl can increase when you take the thyrogen shot? I had in -97 thyroida cancer and got the thyroidea removed and had RAI after. At my last blodtest I had the following blod results: TSH less than 0.05, antithyrogl 11 and thyroglobulin 0.3. I will now have a thyrogenshot and am worried that my levels of thyrogl will increase (could the anti thyrogl also be affeced by the thyrogen shot?). I know my levels are very low, but am wondering how high it could possibly go when the TSH increases.

Thanks a lot for any comments!!

Hi there!

Thyrogen would not directly cause a significant increase in thyroglobulin or antithyroglobulin antibodies normally; though mild elevation in levels may be seen. Increase in thyroglobulin levels after stimulation with thyrogen is often used in clinical practice to diagnose recurrence at early stages. I would suggest discussing the situation in detail with your treating doctor after the results of the test are known.
Hope this helps.

Take care!
