Correlation of free thyroxine index and thyroxine: thyroxine-binding globulin ratio with the free thyroxine concentration as measured by the thyroxine and thyroxine-binding globulin radioimmunoassays

Clinica Chimica Acta, 1978
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 patients.

A RADIOIMMUNOASSAY OF THYROXINE

The Journal of Clinical Endocrinology & Metabolism, 1971
ABSTRACT A simple, sensitive, specific and precise radioimmunoassay (RIA) for measurement of serum thyroxine (T4) is described. The RIA employs rabbit anti-thyroglobulin antiserum as the T4-binding protein. The precision, reproducibility and practicality of the RIA are comparable to those of competitive protein binding assay (CPBA) using serum TBG as ...

Thyroxine Therapy

New England Journal of Medicine, 1994
The availability of sensitive thyrotropin assays allows effective biochemical monitoring of both replacement and suppressive therapy with thyroxine. Whatever target organ is examined, there is tissue thyrotoxicosis if the serum thyrotropin concentration is low, even if the serum triiodothyronine and thyroxine concentrations are normal.

Normalized Serum Thyroxine and Effective Thyroxine Ratio

JAMA: The Journal of the American Medical Association, 1973
To the Editor.— In a recent letter (222:1653, 1972) Mincey compared normalized thyroxine (T 4 N) with the effective thyroxine ratio (ETR) by two in vitro thyroid-function tests utilizing modified competitive techniques of protein binding analysis.

A COMPARISON OF EFFECTIVE THYROXINE RATIO, FREE THYROXINE INDEX AND FREE THYROXINE CONCENTRATION IN CORRECTING FOR THYROXINE‐BINDING ABNORMALITIES IN SERUM

Clinical Endocrinology, 1974
SUMMARYThe effective thyroxine ratio (ETR), a single test of thyroid function which has a highly significant linear correlation with serum free thyroxine (T4) concentration, was assessed for its effectiveness in distinguishing the euthyroid state in subjects with abnormalities of T4‐binding proteins.In patients with low activity of T4‐binding proteins,
