text: does anyone know of any other test besides blood test to test for thyroid problems? my husband had 2 docs tell him that he had all the symtoms of thryoid disease before they ran the blood test and when both test came back they were normal.  he has heard that there is another test that can be done with a dye as an outpatient, does anyone know what they are talking about? and is there any other problem that mimics thyroid disease? in the "alternative health" circles, most will agree that the standard tsh (thyroid stimulating hormone) test doesn't cut the mustard! its the one that most docs do.  it can come back as a normal reading, but in fact the thyroid can be low.  i have run into the same situation myself.  tests say normal, but i have all the symptoms of hypothyroid.  i'd do some research on the net.  too much info to put it all here.  you could check out this link for starters:  http://www.wilsonssyndrome.com/  there are also some links there to get you going.  good luck!
