TSH has been very low (.19, .126, .0050, .
018) FT4 has been elevated leading him to say I am overmedicated. Before each of these tests my meds have been lowered each time. I am to have TSH, FT4, T3, PTH tests today. He said he doesn't have an answer as to why the levels are so off. Could this be a parathyroid issue? Will the PTH test tell for sure? What other tests might need to be done? I have asked you a few questions in the past and I really appreciate your answers!
