I wasn't arguing that, I was suggesting that if it wasn't clear why the tsh level is high or low, to add on a t4 level check. Which is what is currently done, at least in the US.

It's defined by slightly elevated TSH but normal T4 test results. Anybody with that condition would not be helped by what you are proposing. In general, it seems to me that you will get some false negatives when using a less sensitive test result to qualify a more sensitive test result.
