I recently had my Anti-thyroid Peroxidase Antibody tested and it came back at 422. Doctor said she didn't have a range to compare it to and that the report said it was 'non-specific' so she couldn't confirm or deny I had Hashimoto's.
I have looked on the internet and seemed to have found several lab ranges for different NHS hospitals over the UK and they say anything below 50-75 is normal. Does this mean I have Hashi's??
I just want a definite answer!! How can it be non-specific? I either have it or I don't!!
