Probably: In interpreting thyroid hormone levels, you have to consider several things: What is the clinical situation at the time of the lab draw- as stress, medications, even pregnancy can all effect the levels and what they should be. Every lab also has a slightly different 'normal' range depending on how they measure the hormone. Seeing the trend also helps - Are they stable, going up or down?

Depends: was the T3 (liothyronine) free or total? Was a reverse T3 (liothyronine) done? A thyroid panel is incomplete without RT3 (liothyronine). More info on http://drfairchild.blogspot.com/2012/12/proper-thyroid-testing.html
