Thyroid Peroxidase Antibodies - is it normal to have any of these antibodies?

[Guest guest]

Hi everyone,

Our 10-year old daughter is undergoing testing for Hashimoto's disease and

gluten sensitivity so we had our 8-year old daughter tested as well.

Her thyroid peroxidase antibodies came back at 13.0 IU/mL and the doctor says

that less than 20 is " normal " . Although the doctor said that this is normal, I

googled it and some sources say that a person should not have any antibodies

against the thyroid and that any result other than zero is abnormal and should

be rechecked.

Does anyone know if a level of 13 is normal?

Thanks,
