Иммунологическая и инфекционная безопасность компонентов крови является основным критерием качества трансфузионной терапии. Внедрение методов фильтрации крови способствует разработке методов валидации контроля остаточных лейкоцитов в продуктах крови. Необходим простой в исполнении и надежный метод подсчета остаточных лейкоцитов в продуктах крови.</p><p>Целью данного исследования была сравнительная характеристика использования проточного цитометра и гематологического анализатора для контроля содержания остаточных лейкоцитов в плазме крови.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследовании сравнили два метода подсчета остаточных лейкоцитов в 191 образце донорской плазмы, производимой в ФГБУ «НМИЦ им. акад. Е.Н. Мешалкина» Минздрава России, при помощи проточного цитометра (Navios Beckman Coulter) с использованием коммерческого набора реагентов LeukoSure и гематологического анализатора Sysmex XT-4000i.</p></sec><sec><title>Результаты</title><p>Результаты. Все проанализированные образцы плазмы соответствуют требованиям технического регламента. Большая часть образцов имела очень низкие количества остаточных лейкоцитов. Использование проточного цитометра Navios Beckman Coulter позволило определить в 83 % образцах количество лейкоцитов ≤15 кл в мкл, использование автоматического гематологического анализатора Sysmex XT-4000i для подсчета остаточных лейкоцитов в данном диапазоне ограничено чувствительностью прибора и отсутствием аттестованных контрольных материалов с низким содержанием лейкоцитов. Результаты текущего исследования показали, что подсчет остаточных лейкоцитов плазмы крови, оцененный с помощью проточного цитометра Navios Beckman Coulter, дает приемлемые результаты, он также наилучшим образом подходит для образцов с минимальным количеством клеток до 15 единиц в мкл.</p></sec><sec><title>Заключение</title><p>Заключение. Значительная вариабельность содержания остаточных лейкоцитов в образцах плазмы крови свидетельствует о целесообразности проверки содержания лейкоцитов во всех компонентах крови.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Immunological and infectious safety of blood components is considered to be a key condition for high-quality transfusion therapy. The progress of blood filtration methods contributes to the development of methods for the validation of residual leukocyte control in blood products.</p><p>The aim of the study was to compare the efficiency of flow cytometer with hematology analyzer for counting residual leukocytes in blood products</p></sec><sec><title>Methods</title><p>Methods. In this study, we compared the efficiency of two analytical instruments for counting residual leukocytes in 191 blood plasma samples: a flow cytometer (Navios Beckman Coulter) with a LeukoSure commercial reagent kit and a Sysmex XT4000i hematology analyzer.</p></sec><sec><title>Results</title><p>Results. All the samples under investigation met technical regulation requirements. Most of the samples were characterized by a significantly low amount of residual leukocytes, which fact presented a particular scientific interest. The use of a Navios Beckman Coulter flow cytometer and a commercial reagent kit allowed us to detect 15 or lower cells per μL in 83 % of the samples. The use of a Sysmex XT- 4000i automatic hematology analyzer for the calculation of residual white blood cells in this range proved to be limited due to the sensitivity of the device and the absence of certified reference materials with a low white blood cell count.</p></sec><sec><title>Conclusion</title><p>Conclusion. Our results show that a Navios Beckman Coulter flow cytometer with a commercial reagent kit is suitable for measuring residual leukocytes in blood plasma. This instrument is most appropriate for samples with a minimum number of cells. A significant variability of the amount of residual white blood cells in blood plasma confirms the importance of inspecting the content of leukocytes in all blood components.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>компоненты крови</kwd><kwd>остаточные лейкоциты</kwd><kwd>проточная цитометрия</kwd><kwd>контроль качества</kwd></kwd-group><kwd-group xml:lang="en"><kwd>transfusion of blood components</kwd><kwd>residual leucocytes</kwd><kwd>flow cytometry</kwd><kwd>quality control</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">Костин А.И., Майорова О.А., Ложкин А.В. и др.
