I'm getting confused with ideal ranges for free t4 and free t3! Can somebody help my under-medicated brain?!

Am I correct in saying free t4 should be somewhere in the middle, free t3 should be near the top and TSH should be nearer to 0?

I am writing a letter to my GP and definitely don't want to get this info wrong!

I have printed out a copy of the Pulse article, but I'm still a bit lost.

TSH 0.3 - 1.0.

FT4 in the upper quadrant.

FT3 in the upper third.

Thank you so much!
