He is rated OFA Normal, everything is in range other than the Free T3 and Total T3 values which are both low. And amazingly, Dr Dodd has already responsed to my email. She said those low values are usually an indication of "some non-thyroidal issues" but everything else looked good (she even provided the normal sighthound ranges for all of the tests). So, I guess I'll have to figure out what "some non-thyroidal issues" may entail and if it's something I need to address. I guess I'll put a separate post about that.
