Материалы и методы: проанализированы 5 472 показателя ЩФ с 01.08.2013 по 30.04.2017 (672 – диагностическая система Synchron (Beckman Coulter), 4 800 – ADVIA 1800 (Siemens Vista)). Результаты: выявлено 67 (1,2%) низких значений ЩФ у 55 пациентов: 35 принимали глюкокортикоиды; 4 – цитостатики; остальные без терапии (6 – в дебюте ювенильного ревматоидного артрита (3), острого лейкоза (1), синдрома Кавасаки (1), узловатой эритемы (1); 4 – с хроническими заболеваниями желудочно-кишечного тракта; 3 – с легкой формой бронхиальной астмы; 2 – с детским церебральным параличом; 1 – с преждевременным половым развитием). Низкие показатели ЩФ выявлялись чаще при использовании Beckman Coulter (26; 3,87%), чем Siemens Vista (45; 0,94%). Чувствительность «отрезной точки» 150 Ед/л составила 100%, специфичность  – 75,18%; при использовании 100 Ед/л – 56,52 и 88,12% соответственно. Заключение: низкий уровень ЩФ является основным биохимическим маркером гипофосфатазии; в исследовании большинство случаев снижения ЩФ было ассоциировано с приемом лекарственных препаратов. При анализе уровня ЩФ важно использовать референсные значения с учетом возраста и пола, так как унифицированные «точки отсечения» обладают низкой специфичностью и/или чувствительностью.</p></abstract><trans-abstract xml:lang="en"><p>Study objectives: To conduct screening of alkaline phosphatase (ALP) levels; compare the frequency of detection of low ALP levels using different diagnostic systems; evaluate the possibility of introducing a single «cut-off point». Materials and methods: We analyzed 5472 ALP tests were from 01.08.2013 to 30.04.2017 (672 tests been done with diagnostic system Synchron (Beckman Coulter), 4800 tests been done with system ADVIA 1800 (Siemens Vista)). Results: Identified 67 (1.2%) tests (55 patients) with low values of ALP: among them 35 patients been treated with glucocorticoids; 4 with cytostatics; the rest patients without therapy (6 were in the debut of juvenile rheumatoid arthritis (3), acute leukemia (1), Kawasaki syndrome (1), erythema nodosum (1), 4 with chronic gastrointestinal diseases, and 3 with mild bronchial asthma , 2 – with infantile cerebral palsy, 1 – with premature sexual development). Low ALP values were detected more often in cases of Beckman Coulter system using (26, 3.87%) than Siemens Vista (45, 0.94%). The sensitivity of the «cut-off point» 150 U/l was 100%, specificity 75.18%; in case of «cut-off point» 100 U/l figures are 56.52% and 88.12%, respectively. Conclusion: low level of alkaline phosphatase is the main biochemical marker of hypophosphatasia; in the study, most cases of ALP reduction were associated with drug administration. Analyzing ALP level it is necessary to use ALP reference values specified by age and gender, as unified «cut-off points» have low specificity and/or sensitivity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипофосфатазия</kwd><kwd>щелочная фосфатаза</kwd><kwd>глюкокортикоиды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypophosphatasia</kwd><kwd>alkaline phosphatase</kwd><kwd>glucocorticoids</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">Rockman-Greenberg C.
