Do my results show Graves Disease relapse?


So I have just received my results from my Endo, he has happy with my results and I go back in 3 months for a review. I have been suffering bad palpitations, although they have calmed down over the past 2 weeks.

Looking at my latest results, am I relapsing? My TSH was 0.7 in January and then 0.5 in March. I have been off my anti-thyroid meds since December.

FT4 - 17

FT3 - 5.3

TSH - 0.44

Thanks :)

Hi Rubardandcustard really need to see the ranges from your bloodtest to be able to advise you if your overactive, if you have them could you post them for us.

If you are not taking any form of thyroid hormone or anti-thyroid medication, then your decreasing TSH could be a sign that your Graves' is still active. Graves' antibodies are to the TSH Receptor, so a low TSH is the most prominent sign. It can be close to zero even AFTER a thyroidectomy or RAI if the antibodies are still high. This is a page about Graves' tiredthyroid.com/graves.html and why you should measure the antibodies before discontinuing your anti-thyroid meds.

Note that TSH fluctuates in normal people too, so I'd put more weight into symptoms.

Thank you for this link. I am seeing my endo for the first time on 28th April, diagnosed Hyper on 24th Feb. It has been a massive learning curve, but this information on antibodies is the most useful I have seen. I now realise the two tests I have had won't be as useful to the endo as I thought. TPO level of 1300(!), but not tested for TSI. My GP needs to brush up on her thyroid knowledge!
