Have Hashi's - ( 35years!) never felt really well. Last GP wouldn't test T3/T4 - just said I am fine with TSH of 3. 75 . ( I wasn't!!) Made appointment with another GP - much more sympathetic - he actually listened to me me - and put Levo up to 125 , did full bloods( most ok), Gastric parietal cell antibodies(negative), but MCV was 92 - ?too high - while B12 is 353ng/, and Folate 6.6ugl - which I believe are far too low so have started supplementing with advice from the Forum. I also got a copy of the blood results and noticed that GP had requested on the lab form T4 and T4 levels also but the lab DIDN'T do it ! Why should they refuse the GP's request? How can I get these tests done if I can't afford to go private? Also wondering if T3 would help me and if so, where do I get it, how do I know its the "real thing " if I buy on the internet, and how do I begin ?Thanks!
