No T3 test just Serum Free T4 level which is above range 31.7 pmoi/L range is apparently 12.0-22.0. Serum TSH level below range at 0.01mU/L range being 0.27-4.2. Doctor wrote to say these results abnormal. What does it mean. Despite going to gym 3 times a week and swimming have put on a stone in weight. Help! Please. Any observations welcome.
