When to test tsh

[dogtired]

Can anyone tell me when during the day is it best to test tsh......at its highest elevation.

I'm always borderline so the lab never tests t4 levels......feeling crap today!!

[SeasideSusie Remembering]

As early as possible in the morning, preferably before 9am. Fast overnight (you can have water). Depending on your thyroid meds, leave off Levo for 24 hours and T3 for 12 hours. This all gives the highest possible TSH.

If your doctor is judging you on TSH alone then change him quickly! You need to be going by how you FEEL not numbers!

Not easy to find a dr who doesn't treat the tsh as the gold standard!!

What do you mean by borderline? At the top of the range?

[dogtired in reply to dang]

Hello Dang.....anywhere between

4.0 & 4.6

Ok thanks for the info. You should see about finding another doctor who is more knowledgeable or at least open minded about TSH, my GPs are practically garbage at treating my thyroid yet each of them knew to bring my TSH down to 1 or below.

I know it isn't fun, but your health is more important and you're not doing yourself any favours unless you find another doc, if you have a history (with past records) of your TSH being borderline then bring that with you and ask if you can be sent to a specialist who could better interpret the results.
