An evaluation of a heterogeneous enzyme immunoassay for determination of triiodothyronine in serum (Enzymun-Test T3, Boehringer Mannheim) is presented. The enzyme immunoassay was compared with the laboratory routine radioimmunoassay. The precision of both assays was satisfactory at triiodothyronine concentrations between 1.0 and 8.0 nmol/l (coefficients of variation from day to day less than or...

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...

This study was designed to determine the effect of increase hyperthyrodisim on some hormones (Triiodothyronine, thyroxin, thyroid stimulating hormone) and biochemical parameters (creatinine, magnesium) 58 sample used in this at age (25-40 years), where samples were divided into two groups a rate 29 per group. The totals as follows: control group, group patients. It measured hormone Triiodothyro...

Thyroid gland is an essential endocrine that present in the human body. This review highlights production, regulation and disease conditions of thyroid hormones. The controlled with help hypothalamus pituitary brain. production hormones involves five main steps such synthesis thyroglobulin (TG), iodide uptake, iodination thyroglobulin, storage release. two important produced by are Thyroxine (T...

The effects of anaesthesia on serum thyroid hormones were studied in 32 pregnant young women undergoing Caesarean section at term. Eighteen patients received general anaesthesia and 14 lumbar extradural blockade. Maternal serum concentrations of thyrotrophin (TSH), thyroxine (T4), triiodothyronine (T3) and reverse triiodothyronine (rT3) were measured using radioimmunoassay at 0, delivery and 24...
