Thyroxine-Binding Globulin (TBG)
Thyroxine-binding globulin (TBG) is a protein that carries thyroid hormones through the bloodstream and influences how much total thyroid hormone is measured.
A TBG blood test may help explain unusual total thyroid hormone results, particularly when they do not match TSH or free thyroid hormone levels.
