В настоящей работе приведены результаты первых сравнительных испытаний набора реагентов для неонатального скрининга 5q спинальной мышечной атрофии (СМА) и тяжелых форм Ти/или В-клеточных иммунодефицитов (ПИД) производства компании Rossa, Узбекистан. В качестве метода сравнения выступили измерения с использованием набора реагентов EONIS производства компании Revvity, Финляндия. Предварительные результаты показывают согласие результатов выявления делеции экзона 7 гена SMN1 в гомозиготном состоянии двумя методами, а также относительного количественного измерения концентраций TREC и KREC в сухих пятнах крови новорожденных, что открывает перспективы дальнейшей апробации набора реагентов компании Rossa для оценки его аналитических характеристик и определения пороговых значений в целях использования в неонатальном скрининге.</p></abstract><trans-abstract xml:lang="en"><p>The expansion of neonatal screening to include additional diseases requires the introduction of new diagnostic kits, which in turn necessitates multi-stage validation and comparative testing to evaluate their suitability for clinical use. In this study, we present the results of the first comparative assessment of a reagent kit for neonatal screening of 5q spinal muscular atrophy (SMA) and severe Tand/or B-cell primary immunodeficiencies (PID), manufactured by Rossa (Uzbekistan). The comparative analysis was performed using the EONIS reagent kit manufactured by Revvity (Finland) as a reference method. Preliminary results demonstrate concordance between the two approaches in detecting homozygous deletion of exon 7 of the SMN1 gene and in quantifying TREC and KREC levels in dried blood spot samples from newborns. These findings support the feasibility of the tested reagent kit and provide a basis for further validation studies of the Rossa kit to assess its analytical performance and define appropriate cutoff values for implementation in neonatal screening programs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>5q СМА</kwd><kwd>ПИД</kwd><kwd>TREC/KREC</kwd><kwd>неонатальный скрининг</kwd><kwd>сравнительные испытания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>5q SMA</kwd><kwd>PID</kwd><kwd>TREC/KREC</kwd><kwd>newborn screening</kwd><kwd>comparative trial</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Министерства науки и высшего образования Российской Федерации (в рамках реализации мероприятий Федеральной научно-технической программы развития генетических технологий на 2019–2030 годы, соглашение № 075-15-2025-481)</funding-statement><funding-statement xml:lang="en">This study was supported by the Ministry of Science and Higher Education of the Russian Federation (the Federal Scientific-technical program for genetic technologies development for 2019–2030, agreement № 075-15-2025-481)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chien Y.
