Apologies if I make this sound really longwinded! I had a partial thyroidectomy seventeen years ago and was on 100mcg levo until two years ago when an endo let me try 10mcg T3 added to 75mcg. However, after a year he said that the government was pulling the plug on T3, although he acknowledged that it could be bought on the internet and seemed to imply that it was my choice whether or not to go down that route. I assumed that he would see me again (next October) and as the prescription from my own GP surgery continued for 75mcg Levo, I sourced Tiromel and have been continuing with 10mcg, planning to explain this to the endo when I see him. However, I have never told any GPs at my local surgery and now they are insisting that I take their annual thyroid blood test before they can continue issuing my Levo. I made an appointment for next Tuesday morning….but now I’m wondering if I should discuss it with a GP first, as the T3 will cause the TSH to be extremely low and this will raise alarm bells, although I don’t feel confident that there is anyone in my surgery who is really clued in about the thyroid. Also, if I do go ahead with the blood test should I take both T4 and T3 24 hours before it (I normally take them both at 7.30 am …the test is at 10.30am) or should I take the T3 at 10.30pm the evening before i.e. 12 hours before it? I do realize that they will only test TSH and T4. Thanks for any feedback.
