Blood results

Hi I have Graves' disease diagnosed 2011 have been in remission for 2 years.

Lately bloods have been up and down.

Saw consultant today who discharged me back to gp.

Latest results don't feel brilliant

TSH 4.56 range 0.30 - 5.50

T3 4.6 " 0.0 - 7.0

T4 13.1 " 11.5 - 22.7

Any thoughts on these results greatly appreciated

Do you have results for antibodies tests? Can you tell us what antibodies blood tests the Endo/Gp did?



Thyroid peroxidase 191 <34

Thyroglobulin. 394 <115


Those antibodies say Hashi's, not Grave's. That's why you're becoming hypo. You could, possibly, have Graves, too - but probably not. You are very shortly going to need thyroid hormone replacement.


Thank you for your reply much appreciated.


You're welcome. :)



You are becoming hypothyroid. Some people will develop hypothyroidism after a period of hyperthyroidism. TSH 4.56 means your thyroid is failing. NHS won't usually diagnose hypothyroidism until TSH is >5.5 or FT4 is <11.5. Make sure you have a follow up thyroid test in 6 months. Arrange the blood draw early in the morning when TSH is highest, and fast (water only) as TSH drops after eating and drinking.

Thank you Clutter


I'm confused, I thought they told you that you had Graves disease but these antibodies could be Hashimotos. Did they do antibodies tests specific to Graves disease too? Clutter knows more than me. I looked back at your last posts but can't see the Graves antibodies, perhaps I missed them?


Am not sure maybe when I was first diagnosed back in 2011.

I got these antibodies done privately by blue horizon.

Consultant didn't seem interested in antibody results.


That's too bad your consultant wasn't interested in the antibodies because my understand is that it's really important for the correct diagnosis. Ask Clutter or someone more experienced about antibodies for Graves v. Hashimotos.

Could you get a copy of all your blood test results from when you were first diagnosed? I think it's important that you know what your antibodies status is for Graves.

Thank you for your replies back in 2011 didn't have a clue about any of this. But have a better understanding with help from this site. Will try and get

Graves antibody result from first diagnosis


Its just possible they didn't do the right tests so worth checking now you understand more and can make sense of them.


Thank you nanaedake
