We have a private thyroid test done once a year for our son who is now 9 years old.
We have just received his latest test results, TSH, FT4 and TPOAb are all within the reference range, however his TgAb is too high. We were told by the testing company to start monitoring his thyroid health a little more regularly than just once a year but I would like to know if HighTgAb can fluctuate and also what causes TgAb to go high? I have just made an appointment with our GP for next week but I know that our GP will probably not have an explanation for us.
Can anyone help please? Thank you.
