Just had a look back at your previous posts and agree with GG that’s it’s looking like a lab error. I would ask for a retest. On the other point you made re not having access to your previous notes. I would ask whoever you see now if they could ask to have them forwarded. I’m sure that should be possible.
As others have mentioned, my first thought would be a lab error. Mistakes can be made. The first thing that needs to happen is a retest to confirm the result is correct.
McMurtagh, if it was true it would be pretty surprising, particularly with no symptoms at all.
Do you take any T3? Probably the simplest explanation could be if the test was taken in the hours after a T3 tablet.
Another possibility is if you've started any new medication or supplement it could have completely confused the analysis machines.
If you have Hashimoto's this can cause temporary spikes in hormone levels. Thyroid tissue stores hormone as well as makes it, so sometimes as it's destroyed it dumps extra hormone into the blood.
The obvious thing that causes high blood levels is Grave's disease, otherwise known as overactive thyroid.
If you've had Hashimotos for over 20 years your own thyroid is probably all but destroyed, which makes some of these explanations even less likely.
Whenever the possible explanations are very unlikely, just in terms of probability it's more likely to be a mistake at the lab.
Oh, realising this makes me think of another possibility that isn't very likely. Sometimes our need for thyroid hormone can suddenly change quite a bit, I've heard of people having to slash their dose. I think you would have some symptoms, the main time I'm thinking of the person was hospitalised before the cause was found.
I’d imagine I’d have some inkling that something was wrong - ‘ as I said earlier, I feel no different whatsoever.
As someone with Hashi’s, I’ve had the hyper experience - I was positively manic!! Lost loads of weight, couldn’t sit still - exercising for hours every day!
Currently I’m a chubster, wearing additional layers of clothing as I’m freezing at home while my husband is in a short sleeved t-shirt! And I sleep like a bear in hibernation 🐻
I’ve requested the retest and have contacted the Endo I saw last time about an appointment in the New Year - even though it will mean an expensive trip back to UK.
Thank you for being interested in my plight - I appreciate the support offered by this group x
