Your low TSH and thyroid hormones would suggest mild pituitary underperformance. However, CK is usually high in hypothyroidism and B12:low. Given you unusual results your GP should investigate the cause and if necessary refer you to a specialist.
I wouldn't take thyroid hormones until your GGP had ruled out other possibilities.
I had the same results, low TSH (around 1) and both hormones on the low edge with FT3 mostly under. No hashimotos, tried homeopathy, herbs, supplements, nothing helped. Finally I was given T4, also no change, but when dr added T3 - my symptoms disapeared and I feel very good since then
Like jimh111 mentioned also I was told I have mild pituitary underperformance that results in all my hormones to be low. Important is to find a GP that will not ignore your symptoms and take action. Good luck!
Yes, I strongly suspect that TSH not only stimulates the thyroid but also promotes T4 to T3 conversion but am finding it difficult to find hard evidence.
I’d go back to GP. High B12 can be an indication of a liver or some other health issue. Also your thyroid hormones are low but your TSH is low too. Usually TSH would be higher if thyroid hormones low. Your GP needs to look at your test results and signs and symptoms and investigate further.
I am a bit confused about TSh range.Is your TSH 0.3 or 3.And is the range 0.32 to 4 Wondering if there are typos and just want to be clear asI havenot seen these ranges before.
If Iunderstand this correctly then I agree it maybe apituaritary issue. Itmight beworth investigating where tofind a good pituaritary endo on Canada. In Uk we have pituaritary centres of excellence. I would try tomake sure you see someone with aspecial interest in all things pituaritary.
Generally in agreement with the above replies: you'd better seek further medical advice, including specific expertise to arrive at the most credible seeming diagnosis. That would seem the first priority.
That you have been taking no supplements could be seen as a good thing in a number of ways, including that none of your tests results would have been skewed by these.
I'd be interested to know the units of your prohormone "vit D" test: ng/mL or nmol/L ? (US and rest of the world, as a generalisation !). In either case, your result is fine, indicating a "do nothing" situation, which will help matters for now.
There is considerable confusion of this complex multi-systems hormone ( - with many, medics and the lay, not even realising it is working in a very complex, intricate system).
For an intro. to the more correct biochemistry see:
Sewardbound, your GP needs to check a lot more than the tests you've provided here. Liver function, complete blood count, albumin, creatinine, blood urea nitrogen, electrolytes, etc. Full panel of complete blood tests. You may have a viral infection, for example, that causes liver inflammation which results in B12 leaking out of hepatocytes. Anything is possible and focusing only on less than stellar thyroid function is not enough.
