RE: Full Iron Panel

[Guest guest]

Am just about to go downstairs for my dinner, but below is what

I usually send to our members to give to their doctors, I need to look into the

full iron panel and whether there is a need to get all of this done if you

suffer the symptoms of hypothyroidism. Perhaps somebody could do this for me

and if you find some good links as to the reason why a full panel should be

done, please let me know. Don't know off the top of my head where you can get

private iron testing done.

We recommend that all members should ask their GP or

endocrinologist test the following to see whether any of the results are

returned low within the reference range. This is because if low, thyroid

hormone is unable to get into the cells, either your own, or through thyroid

hormone replacement.

Should your GP or endocrinologist tell you that there is no

connection between these minerals or vitamin levels and hypothyroidism, then

copy the following links out to show him/her

Low iron/ferritin: Iron deficiency is shown to

significantly reduce T4 to T3 conversion, increase reverse T3 levels, and block

the thermogenic (metabolism boosting) properties of thyroid hormone (1-4).

Thus, iron deficiency, as indicated by an iron saturation below 25 or a

ferritin below 70, will result in diminished intracellular T3 levels.

Additionally, T4 should not be considered adequate thyroid replacement if iron deficiency

is present (1-4)).

Hi Sheila and group just wondering if anybody

knows of a place in the UK were i can get a full iron panel done and how much

for ?

Or alternatively if possible sheila can you send me in the direction or do you

have to hand some information on why its important to get a full iron panel and

not just iron/transferrin/saturation. As the last time i went to the doc he

would only put me in for iron/transferrin/saturation and said that ferritin is

" waste of money " and i would also like TIBC.

Thanks

Steve
