When major ABO\u2010mismatched grafts are infused, it is imperative that an accurate determination of the incompatible RBC content is made to ensure that the product is safe for infusion. RBC content determination requires the hematocrit (Hct) parameter which can be obtained via manual (directly measured) or automated (calculated) methods.<\/jats:p><\/jats:sec><jats:sec><jats:title>STUDY DESIGN AND METHODS<\/jats:title><jats:p>Ninety\u2010seven apheresis hematopoietic progenitor grafts were assessed for Hct by manual testing and by four commercially available automated hematology analyzer instruments. A clinical model was developed to assess the frequency of unnecessary RBC reductions or alteration in standard infusion practice.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Significant (p\u2009&lt;\u20090.001) differences were observed where the manual Hct value was markedly lower than automated Hct values. At stringent incompatible RBC threshold of 10 mL, the number of preventable RBC reduction procedures ranged from 18% to 69%.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Accurate determination of RBC content of hematopoietic progenitor grafts is essential for patient safety. Despite the rapidity and convenience offered by automated Hct methods, they significantly overestimate the incompatible RBC content of grafts, which may trigger unnecessary RBC reduction procedures or split infusions. In products where automated Hct methods indicate excessive amounts of incompatible RBCs are present, we advise the performance of confirmatory testing with a manual Hct method to ensure that the automated Hct value is not a false positive.<\/jats:p><\/jats:sec>","DOI":"10.1111\/trf.13346","type":"journal-article","created":{"date-parts":[[2015,9,23]],"date-time":"2015-09-23T05:40:59Z","timestamp":1442986859000},"page":"528-532","source":"Crossref","is-referenced-by-count":11,"title":["Comparison of manual hematocrit determinations versus automated methods for hematopoietic progenitor cell apheresis products"],"prefix":"10.1111","volume":"56","author":[{"given":"Scott T.","family":"Avecilla","sequence":"first","affiliation":[{"name":"Department of Laboratory Medicine Memorial Sloan Kettering Cancer Center New York New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven M.","family":"Marionneaux","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Memorial Sloan Kettering Cancer Center New York New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tyler D.","family":"Leiva","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Memorial Sloan Kettering Cancer Center New York New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u2010ann","family":"Tonon","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Memorial Sloan Kettering Cancer Center New York New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Virgil T.","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Memorial Sloan Kettering Cancer Center New York New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine","family":"Moung","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Memorial Sloan Kettering Cancer Center New York New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard C.","family":"Meagher","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Memorial Sloan Kettering Cancer Center New York New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Maslak","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Memorial Sloan Kettering Cancer Center New York New York"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,9,23]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"465","volume-title":"Apheresis: principles and practice","author":"Wingard JR","year":"2010"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007890-197810000-00006"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007890-198204000-00017"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/bmt.2011.135"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.12466"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/MOH.0b013e3282e9a576"},{"key":"e_1_2_7_8_1","first-page":"208","volume-title":"Rodak's hematology: clinical principles and applications","author":"Longanbach S","year":"2015"},{"key":"e_1_2_7_9_1","first-page":"779","volume-title":"AABB technical manual","author":"Davis\u2010Sproul J","year":"2011"},{"key":"e_1_2_7_10_1","first-page":"375","volume-title":"Cellular therapy: principles, methods, and regulations","author":"Delaney M","year":"2009"},{"key":"e_1_2_7_11_1","first-page":"303","volume-title":"Cellular therapy: principles, methods, and regulations","author":"Crosskell M","year":"2009"}],"container-title":["Transfusion"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Ftrf.13346","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/trf.13346","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,14]],"date-time":"2023-10-14T07:41:56Z","timestamp":1697269316000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/trf.13346"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,9,23]]},"references-count":10,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2016,2]]}},"alternative-id":["10.1111\/trf.13346"],"URL":"https:\/\/doi.org\/10.1111\/trf.13346","archive":["Portico"],"relation":{},"ISSN":["0041-1132","1537-2995"],"issn-type":[{"value":"0041-1132","type":"print"},{"value":"1537-2995","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,9,23]]}}}
