I have an underactive thyroid. Been on levothyroxine for years. Few years back got some T3 but late last year my source disappeared. I bought what I thought was T3 from another supplier but you guys on here told me you thought it was NDT. So been taking 3 tablets @ 60mg spread over the day. I also requested a cortisol test, which I know is not overly accurate but I cant afford to do a private saliva test.
Recently had a blood test , I stopped the NDT 24 hours prior to testing. Here are my results;
Serum free thyroxine 14.2 range pmol 12 to 22
Serum free triiodothyronine 4.4 range pmol 3.1 to 6.8
Serum TSH 0.04 mu/l range 0.27 to 4.2
Cortisol 217 no range 133 to 537. (Taken at 9am)
Vitamin D 250H 65 range 50 to 120
They also did other tests, not sure if they're relevant?
Serum calcium, phosphate, protein, albumin, globulin, urea.
Thanks for your help, invaluable as always!
