Make sure that your doctor is checking for FREE T4 and FREE T3. The "FREE" denotation is very important...our hormones cirulate in our blood bound to protein and free frrom protein. When the hormone is bound to protein, it is not active and therefore not a value we really want to check. If your doctor is ordering FREE hormone your are testing for the active amount of hormone in your bloodstream...a much more acurate test.
