title: Thyroid screening with triiodothyronine assay.
abstract: The relative independence of serum T-3 from changes in thyroid binding protein levels makes it a more effective screening test for hyper- and hypothyroidism than the T-4 assay alone. In fact, its efficiency is comparable to that of the free T-4 index.
