We measured serum thyroxine (free and total), triiodothyronine (free and total), thyroxine-binding globulin, and triiodothyronine uptake by talc in 97 normal men and 50 pregnant women. Mean serum thyroxine and triiodothyronine concentrations were higher in the pregnant subjects (104 vs. 78 mug/liter and 1.69 vs. 1.30 mug/liter) because of a higher mean thyroxine-binding globulin concentration (...

N AUTOMATED TECHNIQUE for the determination of serum T31 uptake, based on the AutoAnalyzer, was proposed by Pollard et al. (1); a report of the clinical application of this method followed (2) and minor technical improvements were reported by Webber et al. (3). The latter showed an excellent correlation between the T3 uptake as measured by the automated technique and serum PBI. Continued experi...
