Just to update members since my last post two months ago, I went for my blood test this week and have had T3 level tested on the NHS.
I know others have had the request denied, so just wanted to say I noticed my Gp had put on the form "T3 as previously advised by endocrinologist" so perhaps this made a difference (I'd seen the endo privately a year ago when Gp had refused to increase my levo once 'in range', despite me feeling like death warmed up!).
I'm now on 125mcg levothyroxine as well as B12, B complex, Vit D3+K2, Magnesium & Vit C and am finally feeling 'alive' again. Latest T3 5.7 (3.5-6.5) T4 19.4 (10-21) TSH 0.08
