In order to achieve the lowest TSH reading on our thyroid blood tests, we are always advised to get a blood draw very early morning, on a empty stomach without our meds.
Why then on the Thyroid UK website does it state...........
TSH has a circadian rhythm (24 hour cycle) and levels peak between midnight and 6am?
Surly this would indicate bloods were better drawn in the afternoon when TSH levels must drop?
I'm very confused,
