I just had a telephone consultation with a new endo (UK). He asked me if they could do a Thyroxine Absorption Test on me.
The test involves me taking 750 mg of thyroxine, and then having blood drawn every couple of hours for six hours.
I asked him what would happen if the test showed that I didn't absorb thyroxine. Would I be prescribed Liothyronine? No he said, that wouldn't be possible, so I asked him what was the point of the test.
I have searched for anything on here regarding the test, but found no mention of it. So I wondered if anybody has been offered the test, or taken it?
