free thyroxine index Acronyms free thy·rox·ine in·dex (FTI), an arbitrary value obtained by multiplying the triiodothyronine uptake by the serum thyroxine concentration; it largely corrects for variations in thyroid-bound globulin concentration by providing a clinically valid estimate of the physiolog...
an estimate of the amount of thyroxine-binding proteins can be achieved with the T3-uptake test, and this may be used to give an approximation to the level offree thyroxine(thefree thyroxine index). In recent years this estimate has been superseded by direct measurement of free thyroxine, eit...
Abbreviations: ACTH = adrenocorticotropic hormone; AUC = area under the curve; BIDMC = Beth Israel Deaconess Medical Center; FSH = follicle-stimulating hormone; FT4 = free thyroxine; FT4I = free thyroxine index; IGF-1 = insulin-like growth factor 1; LH = luteinizing hormone; PPV = positive ...
The concentration of thyroxine-binding globulin in the serum can now be measured by a simple and specific radioimmunoassay. Triiodothyronine uptake and measurement of total thyroxine have been combined to yield a free thyroxine index which has been found to correlate with the clinical state of the ...

A comparative laboratory study was conducted to assess the comparability of FTI (free thyroxine index) and measured free T4 (thyroxine) levels in 36 euthyroid women. The 36 women in the study were not pregnant; 17 of them were taking OCs (oral contraceptives). The frequency distribution of fre...

For example, the synthesis of the enzyme glucose-6-phosphatase, which helps synthesize glucose in the liver, is induced by the hormones thyroxine and cortisone but is repressed by insulin. A general theory of the induction and repression of biosynthesis on the genetic level was formulated by the...
