Опубликованные к настоящему времени статьи демонстрируют, что результаты измерения, особенно автоматическими системами, не корректны. Новый люминесцентный иммуноанализ (ЛИА) введен в настоящее время в практику. Высокая аналитическая (6,2 пмоль/л) и функциональная (17,3 пмоль/л) чувствительность позволяет количественно определить очень низкие концентрации в слюне. Концентрация сТ в слюне у здоровых мужчин утром была 369 пмоль/л (медиана) с разбросом 263-544 пмоль/л, что статистически значительно выше, чем у мужчин с андрогенным дефицитом - 215 пмоль/л (медиана) с разбросом 51-249 пмоль/л. Повторное определение сТ слюне (1 раз в 1 нед в течение 5 нед) показало высокую стабильность результатов во времени с коэффициентом вариации 9% (разброс 5-23%). В этом исследовании мы показали, что сТ в утренней порции слюны хорошо коррелирует с вычисленным сТ в крови и у здоровых мужчин (R = О,754, р = 0,001), и у пациентов с андрогенным дефицитом (R = 0,889, р = 0,0001).</p></abstract><trans-abstract xml:lang="en"><p>The study was undertaken to provide evidence that the salivary concentration of free testosterone (FT) well correlates with the serum level of unbound testosterone in men. Recent articles demonstrate that the results obtained by the use of especially automatic systems are incorrect. Anew luminescence enzyme immunoassay has been now put into practice. Its high analytical (6.2 pmol/l) and functional (17.3 pmol/l) sensitivities allow the quantification of minor salivary concentrations. In healthy males, the morning salivary concentration was 369 pl/lmo (median) with a range of 263-544 pmol/l, which is statistically higher than that in males with androgen deficiency (215 pl/lmol/I (median) with a range of 51-249 pmol/l. Once-weekly remeasurement of salivary FT during 5 weeks showed the high stability of results over time with a variation coefficient of 9% (range 5-23%). The study indicated that FT in the morning salivary sample well correlates with the calculated FR in the blood of both healthy males (R = 0.754; p = 0.001) and patients with androgen deficiency (R = 0.889; p = 0.0001).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>слюна</kwd><kwd>общий тестостерон</kwd><kwd>свободный биологически активный тестостерон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>saliva</kwd><kwd>total testosterone</kwd><kwd>free biologically active testosterone</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гончаров Н.
