Normal TSH, T4, T3. High thyroglobulin antibodies.

[BodhiLeo]

Hi,

I’m a 28 year old female, I have been experiencing symptoms connected to hypothyroid for a few years. Requested a blood test from GP September 2020, (request made through practice website, no appointment due to covid and they did not ask about symptoms!) only tested TSH which they told me was borderline and may need further tests in time (did not give numbers). I have now paid for private fingerprick test and results came back today as ‘normal’ aside from TG antibodies which were high. I don’t know what to make of these results and I’m hoping for some clarity or suggestions. Thanks.

TSH 1.47 ml/UL (0.27-4.2)

T4 16.7 pmol/L (12-22)

T3 4.73 pmol/L (3.1-6.8)

TPO 12.6 kI/UL (0-34)

Thyroglobulin Antibodies 285 kI/UL (0-115)

Hi BodhiLeo I don't have any answers for you but I know the forum members will ask you to post the ranges provided by the lab for each test result, as these will be needed for them to interpret the result.

Thank you! I’ll update that now.

Is this the same test? I also have a high result, the Rheumatologist said it was not abnormal.

I don’t really know! I find all the tests quite confusing

No it's not the same test. It's still a thyroid antibody test but is Thyroid Peroxide antibodies (TPO) whereas the OP's out of range test was Thyroglobulin antibodies (Tg).

If your Rheumatologist thinks that a result of 225 when the range is <34 then he needs a maths lesson (point out that < means "less than" so that result is very high over range). You might want to consider finding another Rheumatologist who has at least half a brain.

By the way, your raised TPO antibodies suggest autoimmune thyroid disease, known to patients as Hashimoto's.

thank you, I will talk to my hematologist about this

Was test done as early as possible in morning before eating or drinking anything other than water

Next step is to get vitamin D, folate, ferritin and B12 tested

It was about 11am, and yes only water.
