Thyroid screening with triiodothyronine assay.
نویسنده
چکیده
The relative independence of serum T-3 from changes in thyroid binding protein levels makes it a more effective screening test for hyper- and hypothyroidism than the T-4 assay alone. In fact, its efficiency is comparable to that of the free T-4 index.

Detection of thyroid system-disrupting chemicals using in vitro and in vivo screening assays in Xenopus laevis.
We developed a thyroid hormone (TH) inducible primary screening assay for the identification and assessment of man-made chemicals that interfere with the TH-signalling pathway within target cells. The assay was developed in a Xenopus laevis cell line that was transduced with a self-inactivating (SIN) lentivirus vector (LV) containing a luciferase gene. The luciferase activation in this cell lin...

We compared the clinical value of "Amerlex" (Amersham International) and "Pre-release Coat-A-Count" (Diagnostic Products Corp.) radioimmunoassay kits for free triiodothyronine with that of triiodothyronine, triiodothyronine/thyroxin-binding globulin ratio, and free triiodothyronine index in patients with thyroid disease, pregnant women, oral contraceptive users, thyroxin-binding globulin-defici...
متن کاملDiagnostic value of a modified assay of free triiodothyronine in serum.
The performance of a modified commercial (Diagnostic Products Corp.) assay for free triiodothyronine in serum was evaluated, and its diagnostic value was compared with two other methods for free triiodothyronine estimation in euthyroid subjects and in patients with thyroid dysfunction. No advantage was demonstrated for the modified assay as an index of thyroid status. In conditions involving th...
متن کاملPositive interference in Radioimmunoassay determination of serum total T3
Introduction: Determination of thyrotropin, total and free thyroxine and triiodothyronine are widely used as diagnostic methods for thyroid function evaluation. There have been numerous reports of interferences in thyroid hormone immunoassays. Herein, a prominent positive interference is reported for a radioimmunoassay kit of total triiodothyronine. Materials and Methods: In this study, a total...
متن کاملThyroid functions of neonates with Down syndrome
BACKGROUND We aimed to evaluate thyroid functions and volumes and detect abnormalities in 80 neonates with Down syndrome. METHODS Data about free triiodothyronine, free thyroxine, thyroid stimulating hormone, thyroglobulin and urinary iodine levels, and ultrasonographic thyroid volume were collected. RESULTS Abnormal thyroid function tests were detected in 53.8% of the patients (n = 50) and...
