Thyroid blood tests don't understand

10 Replies

Hi All,Sorry for messing you all about,I never realised I had my personal details showing. So I'll start again.

Can anyone tell me how these blood tests look,as I see my Endocrinologist at the end of the month,and to be honest I don't have a lot of faith in him,he's telling me one minuite I have hypothyroidism then hyperthyroidism ,then your alright we will just keep an eye on you,so I'm getting pretty worried. I would also appreciate any questions you may feel I need to ask. Thank you for your patients.

And thank you hummanbean.

As I said in your first post those bloods look fine, TSH and bone profile normal.

Gemini71, TSH 1.02 is euthyroid (normal). Testing TSH only misses diagnoses of secondary hypothyroidism where TSH remains low-normal but FT4 is bottom/below range.

I don't see how your endo can determine euthyroidism, hypothyroidism or hyperthyroidism without testing FT4 and FT3 in addition to TSH.

So in your opinion clutter,I've just got what I started with,Underactive thyroid. If I've got that wrong forgive my ignorance.

Euthyroidism,is another new word to me.

Gemini71, I think at the very least FT4 should be tested in addition to TSH. Ideally TSH, FT4 and FT3 will be tested.

Gemini71, euthyroid is normal. TSH 1.02 doesn't indicate underactive.

So clutter does euthyroid mean there's nothing wrong.

Gemini, euthyroid means having a normally functioning thyroid. As I said, I believe at the very least FT4 should be tested because having normal TSH doesn't rule out having low FT4.

Hi Gemini71

I think what Clutter is saying is that it would be impossible to diagnose hypothyroid or hyperthyroid based on a TSH result only...you would need to have FT4 and FT3 tested as well. Maybe you can ask your Endo to do these tests next time you go?

i believe Euthyroid means neither hypo or hyperthyroid but those more knowledgeable will hopeful chip in.

I would just like to thank you people for your help,I basically have an idea what your saying,so when I see my Endo,I've got a bit of ammunition. I will also ask for a T4 blood test. Thank you.
