I was finally referred to an Endo about 3 weeks ago, really nice guy who agreed with me that Levo not doing its job for me personally. (I'm on 200mg) anyway he had agreed to trial me on T3, even though he admitted its getting harder for GP's to keep prescribing it. Before I get my prescription he wants a full panel of bloods to rule out any other autoimmune diseases, celiac's, diabetes etc.
I know not to take my levo for 24 hours before testing, should i still take my high blood pressure meds, and do i fast the morning of the test?
Thanks

Assuming that normal thyroid tests are done at the same time then have your evening meal the night before as normal, then nothing but water until after the blood draw - providing of course that it is an early morning blood draw, no-one expects you to fast longer than that. If your blood is taken later in the day then your TSH is going to be lower and eating also lowers TSH to some extent.
I can't answer about your blood pressure meds I'm afraid, maybe someone else knows about that.
Your endo is 1 in a million! Most of them are lieing cowards!! It was absolutely plain and clear by my bloods that I was converting most of my levo to RT3 and to back that result up I had over/out of range TSH AND over/out of range T4 ... He span me a load of blatant rubbish which was nothing short of laughable to get out of prescribing me T3 as all he’s worried about is his obscene NHS salary and NOT his patients ...
I still take my non thyroid meds(for blood pressure, diabetic, fibromyalgia etc) as usual, but stop B Vits ( inc folic acid/ folate) 3/4 days before and stop T4 for 24 hours.
