Омега-3 полиненасыщенные жирные кислоты (эйкозапентаеновая и докозагексаеновая) обладают противовоспалительным эффектом и снижают риск возникновения</p><p>сердечно-сосудистых заболеваний, а их уровень в виде омега-3 индекса используется как маркер эффективности терапии, в т.ч. статинами. В данном исследовании был протестирован стекловолоконный носитель для анализа жирных кислот в сухих пятнах крови (DBS). Показана высокая корреляция между уровнями жирных кислот в цельной крови и DBS (R²=0,98), превышающая показатели целлюлозных носителей. При пропитке носителя 1% раствором бутилгидрокситолуола достигнута стабильность омега-3 жирных кислот на уровне 84,72% в течение трёх недель. Также выявлена линейная зависимость между содержанием омега-3 в цельной крови и эритроцитах (R²≈0,86), что позволяет использовать математические модели пересчёта между фракциями крови. Полученные данные подтверждают потенциал стекловолоконного носителя как надёжного инструмента для анализа жирных кислот в клинической практике и эпидемиологических исследованиях.</p></abstract><trans-abstract xml:lang="en"><p>Atherosclerosis is an inflammatory disease characterized by the accumulation of low-density lipoproteins in the vascular wall and the related immune activation, leading to plaque formation and increased cardiovascular risk. Omega-3 polyunsaturated fatty acids (Eicosapentaenoic and Docosahexaenoic) exhibit anti-inflammatory properties and reduce cardiovascular risk, with the omega-3 index serving as a marker for therapeutic efficacy, including statin response. In this study, a glass fiber carrier for fatty acid analysis in dried blood spots (DBS) was tested. A high correlation was observed between fatty acid levels in whole blood and DBS samples (R²=0.98), outperforming the commonly used cellulose cards. A 1% butyl hydroxytoluene solution applied to the card surface provided omega-3 stability at 84.72% over three weeks of storage. A linear relationship was also found between omega-3 levels in whole blood and erythrocytes (R²≈0.86), supporting the use of conversion models between blood fractions. These findings demonstrate the potential of fiberglass media as a reliable and practical tool for fatty acid profiling in clinical and epidemiological settings.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>омега-3 индекс</kwd><kwd>сухие пятна крови</kwd><kwd>стекловолоконный носитель</kwd><kwd>целлюлозный носитель</kwd><kwd>регрессионный анализ</kwd><kwd>Whatman 903</kwd></kwd-group><kwd-group xml:lang="en"><kwd>omega-3 index</kwd><kwd>dried blood spots</kwd><kwd>glass fiber media</kwd><kwd>cellulose media</kwd><kwd>regression analysis</kwd><kwd>Whatman 903</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">Alfaddagh A., Elajami T.K., Saleh M., Mohebali D., Bistrian B.R., Welty F.K.
