title: Triiodothyronine radioimmunoassay in the assessment of thyroid function.
abstract: This report describes the development of a sensitive, precise, radioimmunoassay for the measurement of triiodothyronine in unextracted serum, documents serum levels of triiodothyronine in various states of thyroid dysfunction, and assesses the role of the triiodothyronine radioimmunoassay as a routine test of thyroid function.
