Анализ показал уменьшение группы высокого риска на первом этапе скрининга галактоземии (ГАЛ) в 17 раз в 2023 году по сравнению с 2022 годом. Для увеличения эффективности неонатального скрининга ГАЛ предложен алгоритм оптимизации с применением теста второго уровня. Определение активности фермента галактозо-1-фосфатуритдилтрансферазы (ГАЛТ) позволяет выявлять ГАЛ I типа вне зависимости от достижения критического уровня ГАО, учитывая более ранее получение образцов крови у доношенных новорожденных.</p></abstract><trans-abstract xml:lang="en"><p>Statistical analysis of complete galactose level was carried out in blood samples of full-term newborns. Samples were obtained on the 4th day of life from children born in 2022 and on the first or second day of life from children born in 2023. The analysis showed (indicated) 17-fold decrease in high-risk group at the first step of galactosemia screening in 2023 compared to 2022. To increase the effciciency of newborn galactosemia screening an algorithm of optimization with second-level test was suggested. Determination of activity of galactose-1-phosphate uridyltransferase (GALT) enzyme allows to detect galactosemia type I regardless from reaching a critical level of galactose.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неонатальный скрининг</kwd><kwd>галактоземия</kwd><kwd>ГАЛТ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>newborn screening</kwd><kwd>galactosemia</kwd><kwd>GALT</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">Badiu Tișa I, Achim AC, Cozma-Petruț A.
