Hi. I'm having a blood test at 8.30 tomorrow morning re 25 increase in levo. I usually take it at night so will miss tonights. Two questions: 1. Do I take tonights levo after blood test tomorrow and take usual dose again tomorrow night? and 2. Do I miss breakfast before test? I'm also having tests for b12, folate, vit d etc. I really had to fight the gp to get these done and felt quite bullied by him. I probably have a bad comment on my records now. Also he wouldn't request full thyroid function. Why are they so ignorant!
