Thyroglobulin level

Hi and a very warm welcome to the online community

I'm sorry that I can't help with your question but I noticed that your post hadn't had any responses yet.

You could post your question in the ask a nurse section of the community and one of the specialist nurses will aim to reply within 2 working days. Alternatively you could give your CNS a call and I'm sure she'd be happy to go through your results with you.

When you have a minute, it would be really useful if you could pop something about your journey so far into your profile as it really helps others when answering or looking for someone with a similar diagnosis. It also means that you don't have to keep repeating yourself. To do this click on your username and then select 'Profile'. You can amend it at any time and if you're not sure what to write you can take a look at mine by clicking on my username.

Hi Martin,

No you shouldn’t worry but you should get your doctor to review your prescription and check your dose as it’s quite possible that you’re not taking enough thyroxine to keep your TSH at a suppression level. The increase in Tg may well be as a result of your TSH not being lower since the level you describe suggests that the TSH is stimulating the production of more thyroglobulin.

I’m going to take a guess that you’re possibly not in the UK as (quick google search tells me) TSH units in the UK arm U/L and I don’t know the conversion of that from ng/mL So I can’t really interpret your TSH change but the units for Tg are the same and the stimulation effect should be the same.

What you shouldn’t fear is that increased Tg means the cancer is back. Once you get the TSH stabilised, fresh Tg tests will tell you if it’s really gone up or not.
