Hi there, I'm confused recent blood test results from doctors. In past tests my doctors has always tested for TSH and FT4 - this time he carried out a whole range of tests but did not include the T4 test.
I have some concerns as my docs advise test result normal yet my weight has shot up by almost a stone within 3 months with no reasonable explanation. i also have a lot of joint pain and tenderness in my achilles.
Can someone please explain to me what the importance of FT4 test is and also T3. Looking back through all my tests I have never ever had my T3 tested
