I finally had a conversation with my GP today. In cornwall they dont do T3/T4 testing as standard. As in my previous question my last blood test showed my TSH was 0.045 on 100mg thyroxine. i have had to wait for the GP to speak to an endo (who I have never met) who wants me to have the following blood tests done. Morning Cortisol, prolactic, Pituatary Function...but still no T3 until they have these results...what does it all mean? Worried now..
