A one‐step approach to thyroid function tests is reported, using Tetralute kits (Ames). Two parameters are obtained simUltaneously ‐ namely, the serum thyroxine (T 4 .) level and the diagnostic thyroxine ratio (DTR), which correlates well with the free thyroxine Index (FTI) as determined by two separate tests‐the T 4 . level and the triiodothyronine resin uptake (T 4 U) estimations. Data presented from patients with a variety of thyroid states prove that the DTR, particularly in combination with the T 4 . level, Is adequate for the assessment of thyroid dysfunction In almost all circumstances.
