I recently had blood work done at a health fair at our local hospital. In the report, my TSH is 4.420, T4 is 7.4, T3 uptake is 27, and Free Thryroxine index is 2.0. I have had weight gain in the last 6 months, irregular heavy periods, waves of depression, fatigue, feel like I'm in slow motion, lack of motivation, forgetfulness, changes in my hair. Should I have further testing done to see if I am hypothyroid?
