On 40mg Carbimazole for hyperactive thyroid.
Blood test results today show Serum free T3 level of 3.1 (range 3.5-6.5) low. Was 10.4 three months ago!
Serum TSH level 74 mu/L (0.35-5.0) high. Was suppressed three months ago.
Consultant had doubled my Carbimazole from 20mg to 40mg! Having three months previously halved it from 40mg to 20mg!
Am I correct in thinking I am now hypo?
