|TSH||0.4||4.5||mU/L (milliunits per litre)|
|FT4||9.0||25.0||pmol/L (picomoles per litre)|
|FT3||3.5||7.8||pmol/L (picomoles per litre)|

A low TSH levels together with a low FT4 levels can indicate a disorder of the pituitary gland

It is well recognised that thyroid problems often run in families and if family members are unwell they should be encouraged to discuss with their own GP whether thyroid testing is warranted
