Laboratory testing revealed a total triiodothyronine ([T.
Thyrotropin (thyroid-stimulating hormone or TSH), free thyroxine, and total triiodothyronine were assessed at weeks 0, 4, and 6.
They found a clinically significant bias in total triiodothyronine (T3) results in samples collected in SST tubes.
BDEs 47, 99, and 100 were significantly and positively associated with free and total thyroxine levels, and with total triiodothyronine levels above the normal range.
 The tests covered by this group are total thyroxine (TT4), total triiodothyronine (TT3), free thyroxine (FT4), free triiodothyronine (FT3), and thyroid-stimulating hormone (TSH).
4]), triiodothyronine resin uptake, and total triiodothyronine levels are elevated.
Phthalate metabolites were inversely associated with serum levels of free and total triiodothyronine, especially in girls, whereas metabolites of di(2-ethylhexyl) phthalate and diisononyl phthalate were inversely associated with IGF-I in boys.
Despite the well-known clinical rationale for measuring free rather than total thyroid hormone, limitations in current methods for the former necessitate retaining the measurements of total thyroxine (TT4)  and total triiodothyronine (TT3) in the clinical laboratory (1, 2).
