I have been on Levo for many years and my level used to change from time to time. Recently I was called by my GP to say my thyroid had gone down a bit and I needed to take 150mgs instead of the 125 mg I had been taking. I may have missed some. I had a blood test again in about 5 weeks and was told it had gone over and I should go back to 125mgs again...I have now had a blood test which says serum THS level 0.8 mIU/L (0.3-5.5)
serum free T4 LEVEL 20 pmol/L (9-25)
Am I hypo or hyper or normal ..
