[Comparative characterization of radioimmunologic and non-isotopic methods of hormonal analysis].

Measurements of 8 hormones (prolactin, FSH, LH, thyrotropic hormone--TTH, estradiol, hydrocortisone, thyroxine, and triiodothyronine--T3) were carried out by the Amerleit system and radioimmunoassay. The hormones were measured in the same blood plasma samples of patients with various endocrine conditions, admitted for examinations to the Endocrinology Center of the Russian Academy of Medical Sciences. Employment of the Amerleit system for hormonal analysis helps obtain the results compatible with the results of RIA for the majority of the measured hormones. The methods for measuring LH, estradiol and T3 are to be improved. The Amerleit system is highly productive and permits getting the results within 3 hrs. A trained laboratory assistant can measure the hormonal levels in 120-160 blood samples within a day. High efficacy of the technology is indispensable in realization of the screening programs. The absence of radioactivity, safety, high productivity, reliability, accuracy and good storage of the kits (up to 6-8 months) are the principal advantages of the Amerleit system over the existent radioimmunologic systems.
