hi everyone, I have a multi nodular goitre for which im on no medication, my most recent blood results came back as t4 16.6 and my tsh 0.32

ive just had them repeated today but am having difficulty understanding what the levels mean when the consultant explains. can anyone just tell me if they think I should be on medication. im fine except for extreme tiredness. thanks in advance

Berniboo, Do you have the lab ref ranges (the figures in brackets after your results) as it helps interpret the results?

TSH 0.32 is low for someone not on thyroid hormone replacement but FT4 doesn't look too low. Were you previously hyperthyroid?

Ask your GP to test ferritin, vitamin D, B12 and folate as thyroid patients are often deficient/low and these deficiencies can cause musculoskeletal pain, fatigue and low mood similar to hypothyroid symptoms. Post your results with the lab ref ranges (the figures in brackets after your results) in a new question and members will advise whether supplementation is required.


Difficult to tell if you should be on medication without seeing the FT3 (which rarely gets done, I know). That is the most important level. You can have a TSH and an FT4 like yours - which don't look too bad in themselves, but you might not be converting, and therefore your T3 could be too low.

I don't know if you can get your doctor to do this, or if you can do it privately, but that would give you a better answer to your question.

Hugs, Grey
