I recently posted my Medichecks results done last week, finger prick done at 15.30 non fasting:-
TSH 1.34 (0.27 - 4.2)
FT4. 13.2. (12 - 22)
FT3. 3.19 (3.1 - 6.8)
I then had NHS tests done 3 days later, fasting and at 7.45am:
TSH 1.52 (0.34 - 5.60)
FT4 12.0 (7.70 - 15.10)
FT3 4.8 (4.30 - 6.80)
Ferritin 11 (11 - 307)
Vit D 130 nmol (have been supplementing)
Vit B12 355
Folate 23.2. (3.80 - 25)
Background
Unmedicated autoimmune thyroid disease with TPO antibodies at 248 ng/ml and TgAb at 1,207 ng/ml. Multinodular normal thyroid gland.
Mildly raised ANA 1:80
Symptoms include weak muscles, shortness of breath, exercise intolerance, mild panic attacks and anxiety and fatigue. Feeling cold and headaches. Frequent palpitations.
I have a long and constant battle with iron deficient anaemia and Raynauds.
My question is I consistently have very low FT3 and although I battle with anaemia I can’t help feeling my low FT3 is contributing to my symptoms. My kind GP is happy to meet up with me to discuss these results but should I be pushing for an endo referral due to a possible conversion issue or thyroid hormone resistance?
I have been reading some scary articles on the effects of low FT3 especially on cardiac health and I already have diagnosed Supraventricular tachycardia and multiple daily ectopics! I reckon I have a huge battle of persuasion ahead of me with the GP !
Thanks so much for any thoughts out there. I have been taking 210mg of Ferrous Fumerate for years but my ferritin keeps dropping 😕. I’m not celiac !
