I have recently been diagnosed with an underactive thyroid and put on a starting dose of 50. I have blood tests in a couple of months to check levels again and assume my dose will increase.
My test results show serum free T4 level of 7.1 pmol/L (7.5 - 21.1) and Serum TSH level of 27.05 miu/L (0.34 - 5.6) but I have no idea what this means and whether my thyroid is very underactive (if that is a thing). I would appreciate any advice and also any thoughts of when I might notice the impact of the medicine.
Thank you in advance
