I am going to see an endocrinologist soon who says to take med as usual, but I have read here advice to not take it until after blood draw. Please help me to know what's best.

My Doctor recently told me to take it 2 hours prior to the test. If you wait until after then you wont necessarily get a true reading.

Well I've took it before and after and the outcome on the last 2 was the same so I don't think it makes any difference I'm just gonna take it as usual as 2 hours before anyways usually xx

Personally I take mine AFTER the blood draw as it skews the readings if you take it before.

I have been told not to take thyroxine before blood test as it will give a false reading. This was proven in a previous blood test and my reading was too high. Thyrixine was lowered, I became a sloth. Read information on Thyroid Org website where there is guidelines for testing, taking etc. I was at doctors on Wednesday, dreading confrontation, but it went surprisingly well. Doctor agreed I self medicate and will look at thyroidorg.uk to update her knowledge.
