I have been on Levothyroxine for many years after having radioactive iodine treatment. My current dose is 125mg per day. I have just got results of latest blood test which I requested as I’ve been feeling so exhausted plus other symptoms (dry skin, trouble sleeping, muscle pain, bad nails, etc) I felt sure it must be a result of under medication. He ran a plethora of bloods but neglected to include FT4 I know my health trust won’t measure for FT3. So the results I have, which may be relevant to the thyroid are
Serum TSH level 0.71 U/ml (0.38 - 5.33)
Ferritin 34 ug/L (30 - 300)
The following were the only things out of range
Serum inorganic phosphate level - above range, 1.51 (0.8 - 1.4)
Serum creatinine level - below range 59 umol/L (62 - 124)
GP has marked the results as No Further Action. I am debating whether to make a follow up appointment with him or not. As my TSH is under 1 I’m thinking maybe it’s not the thyroid. I’d be really interested to hear what others think.
