That test was NOT a TFT (thyroid function test) It was just a TSH test, which is pretty useless. However, it was successful in getting you treated. You need a full test in 6-8 weeks (fasting etc again). Do not take levo for 24 hours before test. Then you should be given a 25mcg increase until symptoms have gone, TSH is under 1 and free T4 and free T3 are in the top part of their ranges. Take care
