Thyroid antibody tests - confused

[Lovehelp]

Hi,

I have been looking at a private test for anti bodies s per suggestions in replies from my previous posts. I have just read on one set:

Anti -TPO Antibodies - 4 - U ( 0.30-5.50)

what does this mean? can anyone help?

[SeasideSusie Remembering]

Do you mean that is your result? Or that you have seen that result online somewhere and if so can you please link to it. That is a very strange range for a TPO antibody test, it's usually 0-34 or 0-60 that we see here on the forum. The range that you have given (the figures in brackets) looks more like the range for a TSH test, in fact it is the range for TSH that you quoted in your previous post.

I do seem to have extreme and strange blood results!

Yes this was on my first blood test result, I did a typo, it should have been

Anti- TPO Antibodies 4 U ( 0-35 IU/ml)

Does this help?

Anti- TPO Antibodies 4 U ( 0-35 IU/ml)

Your antibodies are very low in range which is a negative result, which means this result does not confirm autoimmune thyroid disease (Hashimoto's). However, it is possible to have negative TPO results and have positive Thyroglobulin (Tg) antibodies which can sometimes suggest Hashi's. It's also possible to have Hashi's without positive antibodies.

Have you only had antibodies tested once?

If this was from a private test, did you also have Tg antibodies tested?

The antibody tests to confirm Graves Disease (overactive) are TSI and TRAb.

The bit in parentheses is the laboratory's reference range for a measurement in your blood test that denotes a meaningful presence of antibodies.

Assuming you've quoted to us a result, the number after "antibodies" would be the value in the blood tested, followed by the unit of measure. Otherwise this number is referring to how much blood they need drawn to send it through the test protocol.

A caveat here: I have most of the signs of Hashimotos but the antibody tests show nothing meaningful. The endocrinologist shrugged and said, "it's still treated the same way."
