(just) are you hypo or euthyroid?

Technically you are 'subclinical hypothyroid', as TSH is

abnormal (hypowards) but thyroid hormone levels are normal. At

least that is how some define subclinical hypothyroidism.

I hate the phrase " subclinical " as it implies not worth

treating, or not a severe case, but we all know people vary, as

do their demands. For say an Olympic hurdler may have different

expectations of her body, than the average homemaker (if that's

the PC, US, term).

would appear to be hypo not hyper, but I think Terry has

queried that already.

fT3 belongs near the top of it's range, dragging along the

bottom of the fT3 range might technically be " normal " , but I

suspect the assumptions of what is normal fT3 suffer from

similar issues to the TSH range, although conversely fT4 seems

to usually be towards the bottom of it's range. Anyone got good

frequency distribution data from these tests?

BTW: I emailed the TSH range issues (NACB advice and all that)

issue to the radio 4 'More or Less' team (who report on abuse of

mathematics and statistics), no reply yet, but I figured it

wouldn't hurt.
