Radioimmunoassay and automated enzyme immunoassay for the determination of thyroxine.

چکیده
The EMIT homogeneous enzyme immunoassay for the determination of thyroxine (T4) was adapted to an automatic analyser (Type Kem-O-Mat) and compared with a conventional radioimmunoassay. Sera from 92 patients whose thyrometabolic status was being examined, and control sera with 3 different T4 concentrations were analysed by both methods. Day-to-day analyses of the control sera gave variation coefficients between 6 and 10% for both methods. The mean value for T4 in the patients sera was 111 nmol/l (8.6 microgram/dl) determined by the enzyme immunoassay and 109 nmol/l (8.5 microgram/dl) determined by the radioimmunoassay; the correlation coefficient was r = 0.9.

Homogeneous enzyme immunoassay for thyroxine compared with a radioimmunoassay technique.
A homogeneous enzyme immunoassay (EMIT) for serum thyroxine determination has been evaluated. It was also compared to our routine method, a radioimmunoassay with use of a commercial kit, Tetra-Tab RIA. Within-day precision was very similar for the two methods, the CV ranging from about 2.5% at 150 nmol of thyroxine per liter to about 5.7% at 25 nmol/L. The two methods were compared by running 1...
متن کاملSemiautomated homogeneous enzyme immunoassay of total serum thyroxine with a kinetic analyzer.
A new semiautomatic procedure for determination of total serum thyroxine was adapted to a kinetic analyzer, LKB 2086 Mark II. The ABA thyroxine assay kit was used, and although the assay procedure was modified, the advantage of small reagent volumes, short measuring times, and automation were retained. The results were analyzed off-line with a programmable desk-top calculator. The method has a ...
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 کاملEvaluation of homogeneous enzyme immunoassay of serum thyroxine with use of bichromatic analysis.
We evaluated the homogeneous enzyme immunoassay ("EMIT") of serum thyroxine with use of an ABA- 100 Bichromatic Analyzer, modified with an auxiliary dispenser syringe and a dual probe assembly. The modification allows two reagents to be dispensed at one time. The sera must be pre-treated with 0.1 mol/liter NaOH. The procedure thereafter is entirely automated. Twenty-four patients' samples may b...
متن کاملContinuous-flow enzyme immunoassay for thyroxine in serum.
We have evaluated a fully automated thyroxine assay involving the use of a homogeneous enzyme assay and a Technicon AutoAnalyzer II continuous flow system. Comparison by regression analysis with a thyroxine radioimmunoassay kit method gave a slope of 0.82 and a y-intercept of 7.81 micrograms/L (SE 0.86 microgram/L, r = 0.95). Within-run precision yielded CVs of 1.0-6.1%, between-day CVs were 2....
