Nevertheless more simple and cheap approach with high sensitivity is needed for routine PNH screening. The aim of present study was to investigate the applicability of simplified two-color (FLAER/CD15) flow cytometry for PNH clone screening. Search for FLAER-negative granulocytes was performed in 259 peripheral blood samples obtained from the patients with suspected PNH. Symplified analysis results were compared to the multicolor data. Both in test cohort (n = 216) and validation cohort (n = 43) FLAER-negative granulocytes detection results correlated well with conventional cytometric test findings. Simplified approach diagnostic sensitivity achieved 100% while rate of false positive results was very low (2.63% in test cohort and 0% in validation cohort). Thus two-color detection of FLAER-negative I granulocytes is effective test as a screening for presence of PNH clone. Nevertheless the positive result of screening investigation should be always confirmed by multicolor assessment of PNH clone size among erythrocytes, granulocytes and monocytes.</p></abstract><trans-abstract xml:lang="ru"><p/></trans-abstract><kwd-group xml:lang="ru"><kwd>пароксизмальная ночная гемоглобинурия</kwd><kwd>проточная цитометрия</kwd><kwd>FLAER</kwd><kwd>paroxysmal nocturnal hemoglobinuria</kwd><kwd>flow cytometry</kwd><kwd>FLAER</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Parker CJ.
