Determination of free thyroxine in serum by radioimmunoassay.
We describe a sensitive and specific radioimmunoassay for free thyroxine, directly determined in the diffusate obtained from equilibrium dialysis of serum. The intra- and interassay precisions were 7.5 +/- 0.27 and 9.1 +/- 0.58 ng/liter (mean +/- SD), respectively. The free thyroxine concentrations of normal persons and patients with thyroid disease were as follows: normal, 7.6 +/- 1.7; euthyro...
متن کاملThyroxine-binding by Serum
The occurrence of hypercholesterolemia, lowered basal metabolic rate and depressed serum proteinbound iodine in the nephrotic syndrome has directed attention to the thyroid gland in this disorder. Although hypothyroidism has been suspected, these patients are usually considered, on clinical grounds, to be euthyroid, and they fail to respond in a specific manner to even large doses of thyroid ho...
متن کاملSerum Thyroxine (t4) and Thyroid Stimulating Hormone (tsh) Levels in Cord Blood of Newborns in Lahore
Objective: The primary aim of this study was the early detection and treatment of hypothyroidism in neonates. This paper describes the determination of cord blood serum T4 and TSH levels, their mean levels, reference ranges and interrelationship. Design: Retrospective analysis of serum T4 and TSH levels in 1153 cord blood samples collected and analyzed during July 1998 to June 2000. Setting: Ce...
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 کاملRapid determination of thyroxine binding proteins of human serum.
A simple method is described for determing thyroxine binding proteins in human serum by electrophoresis at pH 8.6, using cellulose acetate membrane as the supporting medium. The procedure had high reliability in sera of normal subjects, pregnant women and patients with decreased thyroxine binding capacity of thyroxine binding globulin.
