A Reliability of steroid radioimmunoassays. book (RIA), in order to be reliable, should have a high precision and a high accuracy. The high precision means that repeated measurements (shots) are as close to each other as high accuracy means that the measured values describe, on the average, the true contents of a steroid in a sample as authentically as by: The effect of the type of biological material investigated on assay accuracy could be seen in a very distinct manner in a study (M.

Biases. Abstract. Radioimmunoassay (RIA) is currently one of the most widely applied of all immunoassay procedures. The increasing application of this technique in many routine clinical diagnostic tests has resulted in requirements for improved reliability and reproducibility, greater rapidity and.

Testosterone is a steroid hormone. Other steroids in the body include cholesterol, bile acids, vitamin D, and hormones of the adrenal glands and ovary. The majority of circulating testosterone in men comes from production in the interstitial cells of Leydig at the testicles.

Die Entwicklung des Radioimmunoassays (RIA) geht auf Untersuchungen von Yalow und Berson [1, 2] in den fünfziger Jahren zurück. Ihnen gelang die Bestimmung von Insulin im Serum unter Verwendung von Antikörpern gegen Insulin und J-Insulin, das mit dem nicht markierten Insulin um die Bindungsplätze am Antikörper konkurrierte.

Since the symptoms of hypogonadism may be nonspecific, and the signs of testosterone deficiency can be subtle and slow to develop, the assessment of testicular function relies heavily on laboratory testing. The laboratory diagnosis of hypogonadism is based on a consistent unequivocally low serum total testosterone level, but normal ranges vary with different methods and among laboratories.

Cholesterol, triglycerides, and high-density lipoproteins are important constituents of the lipid fraction of the human body. Cholesterol is an unsaturated alcohol of the steroid family of compounds; it is essential for the normal function of all animal cells and is a fundamental element of their cell membranes.

It is also a precursor of various critical substances such as adrenal and gonadal. endocrine monitoring of reproduction and stress. items to an animal is another way to collect saliva samples. Samples should be frozen aft er collection, and most assays require fairly extensive extraction procedures.

Some com-mercial companies have developed assays specifi c for saliva to avoid problems associated with matrix eff ects. Urine. The established approach to the evaluation of ovarian function and endocrine disorders in the woman is based on serial biochemical analyses of hormones, such as estrogen, progesterone, luteinizing hormones and their metabolites (Albertson and Zinaman, ).More recently, the analysis of hormonal substances that participate in embryonal development of gonads has contributed still further to.

Purpose To examine the effects of a 1-year exercise intervention on sex hormone levels in postmenopausal women and whether any effects are mediated by changes in body fat composition.

Methods We randomly assigned sedentary postmenopausal women (age 50 to 69 years, body mass index of 22 to 40 kg/m2) to an exercise intervention (n = 96) or a control group (n = 93).
