I have Hashimoto's. I've been on Levothyroxine for 6yrs. I had my blood tested this week, as I'm still experiencing symptoms. Do these results look normal?
Serum free t4 level18.6 pmol/L (10.00-22.00)
Serum tsh 0.51 mU/L (0.10-4.00)
I'm in the process of finding out why I'm still syptomatic. The gp will only do the two tests, so I'm thinking I'll need to go private to have the full range of Thyroid tests.
