Iron deficiency leads to the development of iron deficiency anemia, one of the most common diseases in the Russian Federation; excess iron induces oxidative stress. In this way, the diagnostics of iron metabolism is an important applied problem.</p> <p><bold>The aim of the study. </bold>The aim of the study was to establish reference intervals for serum iron, measured not by the routine method, but by the ICP-MS method, on a large sample; study of gender and age fluctuations of the level of serum iron; study of the relationship between the concentration of iron and the levels of ferritin and transferrin in the blood serum.</p> <p><bold>Material and methods. </bold>The study was performed on the basis of a database of laboratory analyzes. The number of laboratory tests for ferritin, transferrin, iron in serum was 6786, 1809, 13161, respectively. When determining the reference intervals, the Hoffman method was used.</p> <p><bold>Results. </bold>It was found that the concentration of iron in the blood serum among women is lower than among men, and this tendency persists up to 45–50 years, there are no differences in the later age period. The concentration of serum iron positively and statistically significantly correlates with the level of ferritin in all age groups in the total sample and in the group of women; among men, statistically significant positive correlations were found only in the age groups of 18–25 years and older than 56 years. Correlations of iron concentration with the level of transferrin are less intense: statistically significant correlations were found in the total sample in the age groups of 26–35 years and 46–55 years.</p> <p><bold>Conclusion. </bold>When calculating the reference intervals of serum iron, it is necessary to consider the gender and age dynamics of deviations. Aging processes have a greater impact on iron metabolism for women than for men.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Железо – один из основных элементов для поддержания жизнедеятельности организма. Недостаток железа приводит к развитию железодефицитной анемии, одного из самых распространенных заболеваний в РФ; избыток железа индуцирует окислительный стресс. В связи с этим диагностика обмена железа является важной прикладной задачей.</p> <p><bold>Цель исследования.</bold> Цель исследования – установление референсных интервалов сывороточного железа, измеренного не рутинным методом, а с помощью масс-спектрометрии с индуктивно связанной плазмой (ИСП-МС), на большой выборке обследуемых; изучение половозрастных колебаний уровня сывороточного железа; изучение связи концентрации железа с показателями ферритина и трансферрина в сыворотке крови.</p> <p><bold>Материал и методы.</bold> Исследование выполнено на основании базы данных лабораторных анализов. Количество лабораторных тестов на ферритин, трансферрин, железо в сыворотке составляло 6786, 1809, 13161 соответственно. При определении референсных интервалов использовался метод Хоффмана.</p> <p><bold>Результаты.</bold> Выявлено, что концентрации железа в сыворотке крови среди женщин ниже, чем среди мужчин, и данная тенденция сохраняется до 45–50 лет, в более позднем возрастном периоде различия отсутствуют. Концентрация сывороточного железа положительно и статистически значимо коррелирует с уровнем ферритина во всех возрастных группах в общей выборке и в группе женщин; среди мужчин статистически значимые положительные корреляции выявлены только в возрастных группах 18–25 лет и старше 56 лет. Корреляции концентрации железа с уровнем трансферрина менее выражены: статистически значимые корреляции выявлены в общей выборке в возрастных группах 26–35 лет и 46–55 лет.</p> <p><bold>Заключение. </bold>При расчете референсных интервалов концентрации сывороточного железа необходимо учитывать половозрастную динамику отклонений. Процессы старения в большей степени оказывают влияние на показатели обмена железа у женщин, чем у мужчин.</p></trans-abstract><kwd-group xml:lang="en"><kwd>iron</kwd><kwd>ferritin</kwd><kwd>transferrin</kwd><kwd>blood serum</kwd><kwd>reference values</kwd><kwd>ICP-MS</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>железо</kwd><kwd>ферритин</kwd><kwd>трансферрин</kwd><kwd>сыворотка крови</kwd><kwd>референсные интервалы</kwd><kwd>ИСП-МС</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Abbasi U., Abbina S., Gill A., Takuechi L.E., Kizhakkedathu J.N.
