Help Me Make Sense Of My Blood Test Results

[zes]

I have never read blood panels or blood test results before so I just want to make sure with more knowledgeable people here what the results mean. I am also new to peating so any suggestions on what to improve on is highly appreciated. Thanks

(My t4 is slightly too high isn't it? TSH too. I wanted to know if I am hypothyroid.)
