Following advice in this forum to request a T3 test, I now have my blood test results and would be grateful for interpretation. Quick summary again, I have a total thyroidectomy over 10 years ago and was on 200mg levothyroxine until 16months ago when my consultant reduced dose to 150mg due to my age, not in response to blood tests. I now have every multiple symptoms that I think are due to this and that I may be hypothyroid.
Serum TSH 4.7 mu/L [0.4 -5.5]
Serum Free T4 18.1 pmol/L [11.5 - 22.7]
Serum Free Triiodothyronine 2.9 pmol/L [3.5 - 6.5]
Vit D 105.8 nmol/L ( I have been taking weekly supplement due to prior low level)
Folate 14.0 ug/L [5.4 - 24.0]
Ferritin 76 ug/L [10.0 - 307.0]
B12 1175 ng/L [210.0 - 910.0] I have been taking a supplement
I have a note on my results print out to speak to the Doctor regarding my thyroid set of results, and there is also a note on there saying that the T3 is below range. Is the level in my results low enough to make me have all these symptoms? Also is the TSH hormone suppressed enough as I had a thyroidectomy due to cancer.
You are very hypo! Your TSH isn't suppressed at all, it should be something like 0.001 if you've had cancer. My goodness, your doctor is an idiot! Yes, the level of your FT3 is low enough to cause you an awful lot of symptoms. It should be up near the top of the range.
Your TSH is so high because your FT3 is below range. And you really aren't converting very well. So, ideally, rather than increase your T4 back to 200 mcg (you needed it that high because you weren't converting very well) your doctor should leave the T4 where it is, and introduce some T3. But, by the sound of your doctor, I doubt there's much chance of him doing that.
I was very shocked by the TSH result to be honest, I did not know the level it should be, but anyone looking at that range can see it is nowhere near suppressed.
It was my ENT consultant that did the original operation that put my dose down, he is not an endo, so I guess that explains the nonsensical dose reduction.
Thank you for your help interpreting the results. I have a follow up with GP next Wednesday to go through results so I will be ensuring I pick up all of these issues with him.
