I believe it's ok. It's showing that you do have antibodies present but not high enough on the range to cause problems. Don't know for sure. But I think this question deserves a bump up for those who are more knowledgable than I.
We all have antibodies, its when they attack our thyroids as a foreign object that a problem begins. If your antibodies are below the range then I think you are o.k., I believe 0-40 is considered a normal amount for the average person.
dea4 - how would that be interpreted when the reference range is 0.0-2.0?
My result was 1.1..
All labs use different ranges for most all tests, within the labs range on antibody testing I believe would be considered a normal amount for the average person. Its not that if you go to one lab and then another your result would be the same so you would be out of range at one lab and in range at another, the end result is pretty much the same, its just the way they conduct the test and the measurement system they use.
