I had a variety of test ran on my thyroid and I'm waiting to see the DR. My question is the TPOAb reference rang is 0-34. Mine came back as 9 IU/ml. Is this still considered normal or abnormal? I also have a family history of HyperT and HypoT (not sure if that matters) Thanks.

  • Ok....Thanks. Let me see if I can rephrase my question. If a reference range is 0-34, Would 9 be considered negative? (Not sure if its allowed this way) I do see my DR in a few days.

  • Not sure what your asking, but as long as its not refering to anyone specific you should be fine. All I and my phrases should be avoided. We can evaluate the question again after editing and if it's within guidelines you should be all set.

Normal. A result of 9 where the reference range is 0 - 34 indicates that you're within the normal range. For this test, an abnormal result would be a value over 34 because it's not possible to have a result below zero.

Keep in mind that each testing lab can different reference ranges, and they can differ over time too.
