Агрегацию тромбоцитов можно предотвратить, применяя другие варианты антикоагулянтов или дополняя их аминогликозидами. При ЭДТА-зависимой тромбоцитопении функция тромбоцитов не нарушена, проявлений геморрагического синдрома нет. В данной статье рассмотрен клинический случай выявления ЭДТА-зависимой псевдотромбоцитопении у ребенка 2 лет 6 месяцев, что представляет практический интерес, поскольку у детей данное явление встречается довольно редко. Было зарегистрировано низкое число тромбоцитов в общем анализе крови у ребенка в крови, стабилизированной антикоакулянтом К2ЭДТА. Подсчет тромбоцитов в образце крови, стабилизированной цитратом натрия, был в пределах референтных интервалов.</p></abstract><trans-abstract xml:lang="en"><p>Ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia is the phenomenon of a spurious low platelet count due to antiplatelet antibodies that cause platelet clumping in blood anticoagulated with EDTA. The aggregation of platelets in EDTA-dependent pseudothrombocytopenia is usually prevented by other anticoagulants, such as sodium citrate. EDTA-dependent pseudothrombocytopenia has never been associated with hemorrhagic diathesis or platelet dysfunction. In this article, a 2,5-year-old boy with EDTA-dependent pseudothrombocytopenia is presented because of rare presentation. We report that EDTA can induce platelet clumping, and thus spuriously low platelet counts. However, aggregation of platelets was not detected in blood samples with sodium citrate, and platelet count was normal.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>общий анализ крови</kwd><kwd>тромбоцитопения</kwd><kwd>ЭДТА</kwd><kwd>цитрат натрия</kwd><kwd>псевдотромбоцитопения</kwd><kwd>тромбоциты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thrombocytopenia</kwd><kwd>complete blood count</kwd><kwd>ethylenediaminetetraacetic acid</kwd><kwd>citrate</kwd><kwd>pseudothrombocytopenia</kwd><kwd>thrombocyte</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">Lin J., Luo Y., Yao S., Yan M., Li J., Ouyang W., Kuang M.
