Effective thyroxine ratio and free thyroxine index
Brien, T. G., Fay, J. A., and Griffin, E. A. (1974). Archives of Disease in Childhood, 49, 225. Thyroid status in the newborn infant: effective thyroxine ratio and free thyroxine index. The effective thyroxine ratio (ETR) was determined in 28 term and 17 premature infants at birth and in 17 infants aged 0 to 6 weeks. The mean values found were significantly higher than those in 20 adult euthyro...
متن کاملComparison between determination of free thyroxine index and effective thyroxine ratio in human serum.
Four thyroid function indices were determined in the sera of 181 patients: total thyroxine (T-4), the triiodothyronine resin uptake (T-3 B.C.-index), the free thyroxine (T-4) index, and the effective thyroxine ratio (E.T.R.).A statistically significant correlation between the free T-4 index and E.T.R. could be established though this correlation seemed to be worse than could be expected from th...
متن کاملtotal thyroxine, free TBG capacity, and free thyroxine index using Sephadex G-25 and '25I-labelled triiodothyronine and thyroxine
SYNOPSIS A trial was carried out on 134 patients of new kits (Ames Co) using columns of Sephadex G-25 for the determination of serum total thyroxine (Tetralute test) and for the indirect estimation of serum free thyroxine-binding globulin capacity (Trilute test). Both new methods were quicker and easier than the reference resin methods and of similar precision. The two measurements when combine...
متن کاملThyroid Status: The Effective Thyroxine Ratio
serum was performed in the presence of test serum itself and expressed as a fraction (Effective Thyroxine Ratio, E.T.R.) of serum thyroxine concentration similarly determined in normal serum. From studies of serum obtained from euthyroid, hyperthyroid, and hypothyroid patients and from euthyroid pregnant women and women taking contraceptive (oestrogen) medication, the E.T.R. estimation has been...
متن کاملRelation between free triiodothyronine/free thyroxine ratio, echocardiographic parameters and mortality in dilated cardiomyopathy.
BACKGROUND Abnormalities in thyroid function are frequent in patients with heart failure and are associated with increased mortality. However, the relation between thyroid hormone levels and echocardiographic parameters has not been investigated sufficiently. AIM The aims of this study were to investigate the correlations of thyroid hormone levels with echocardiographic parameters and to eval...
