After reading posts on this forum I have, for the first time, requested a copy of my recent Thyroid function test results from my GP and I am shocked and confused. The shock comes from a Serum TSH reading of <0.01mu/L (0.27-4.2) and confusion that the unit measurement is mu/L rather than the unit mlU/L normally seen.
Serum free T4 level-13.1 pmol/L (10.0-21.0)
Serum free T3 level 3.7 pmol/L (3.5-6.5)
Serum ferritin 205 ug/L
Serum vitamin B12 376 ng/L
What does this abnormally low TSH count indicate? I am taking 100mcg T4 and 20 mcg T3 (10mcg am and 10mcg pm) daily for my hypothyroidism diagnosed 8 yrs ago. I had a goitre and thyroidectomy at the age of 19, 52 yrs ago. I am currently feeling lethargic, lacking stamina, hair thinning and putting on weight.
I also take Premique hormone replacement therapy and Adalat for moderatly high blood pressure. Please help me make some sense of this.
