The result is summarized in the following.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Genotyping was carried out by an external service provider using the competitive allele specific PCR (KASP) technology. The genotypes were returned to the blood bank and translated into phenotypes by a proprietary IT application.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total, 65 alleles from 16 blood group systems (ABO, MNS, Rh, Lutheran, Kell, Duffy, Kidd, Diego, Yt, Dombrock, Colton, Landsteiner\u2010Wiener, Cromer, Knops, Vel, secretor status) and the HPA1, HPA5 and HPA15 antigens were interrogated. After translation, phenotypes were imported into the laboratory information management system of the blood bank. The results from 31,538 genotyped blood donors were used to calculate the allele frequencies for a Danish blood donor population. <jats:italic>ABO<\/jats:italic> genotyping was done for sample ID purposes. Determination of the 1061delC single nucleotide polymorphism (SNP) (NM_020469.2), most frequently characteristic of <jats:italic>ABO*A2<\/jats:italic>, was validated against a series of 1287 samples with <jats:italic>Dolichos biflorus<\/jats:italic> lectin determination of the A1 phenotype.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We report allele frequencies and phenotype frequencies for 16 blood groups from a total of 31,538 genotyped blood donors. Blood products were supplied from a total of 64,312 active blood donors, and of these active blood donors 25,396 (39.5%) were genotyped. These donors represent a valuable resource for patient treatment. This genotyping has enabled the provision of rare genotyped donor blood for patients with alloantibodies and rare reagent cells for serology.<\/jats:p><\/jats:sec>","DOI":"10.1111\/vox.13524","type":"journal-article","created":{"date-parts":[[2023,9,6]],"date-time":"2023-09-06T11:28:23Z","timestamp":1693999703000},"page":"980-987","source":"Crossref","is-referenced-by-count":3,"title":["Blood donor genotyping for prediction of blood group antigens: Results from 5\u2009years' experience (2017\u20132022)"],"prefix":"10.1111","volume":"118","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7251-5754","authenticated-orcid":false,"given":"Klaus","family":"Rieneck","sequence":"first","affiliation":[{"name":"Department of Clinical Immunology Section 2034, Rigshospitalet  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9663-8476","authenticated-orcid":false,"given":"Grethe Risum","family":"Krog","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Section 2034, Rigshospitalet  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederik Banch","family":"Clausen","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Section 2034, Rigshospitalet  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoffer","family":"Egeberg Hother","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Section 2034, Rigshospitalet  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Morten Hanefeld","family":"Dziegiel","sequence":"additional","affiliation":[{"name":"Department of Clinical Immunology Section 2034, Rigshospitalet  Copenhagen Denmark"},{"name":"Department of Clinical Medicine University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,9,6]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/vox.13361"},{"key":"e_1_2_9_3_1","first-page":"193","article-title":"Performance evaluation study of ID CORE XT, a high throughput blood group genotyping platform","volume":"16","author":"Lopez M","year":"2018","journal-title":"Blood Transfus"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4939-2690-9_5"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tmrv.2012.10.001"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.13168"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.21307\/immunohematology-2019-075"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1182\/bloodadvances.2020001894"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.15473"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.15474"},{"key":"e_1_2_9_11_1","volume-title":"The blood group antigen \u2009FactsBook","author":"Reid ME","year":"2012"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1537-2995.2008.01914.x"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajt.2022.12.017"},{"key":"e_1_2_9_14_1","first-page":"1","article-title":"Genotyping of blood donors for timely procurement of rare antigen\u2010negative blood: a case story of acute HTR and anti\u2010Coa","volume":"14","author":"Kielsen K","year":"2023","journal-title":"J Blood Disord Transfus"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.96.24.13973"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/vox.12185"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/vox.12085"}],"container-title":["Vox Sanguinis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/vox.13524","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,15]],"date-time":"2023-11-15T21:30:42Z","timestamp":1700083842000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/vox.13524"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,9,6]]},"references-count":16,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2023,11]]}},"alternative-id":["10.1111\/vox.13524"],"URL":"https:\/\/doi.org\/10.1111\/vox.13524","archive":["Portico"],"relation":{},"ISSN":["0042-9007","1423-0410"],"issn-type":[{"value":"0042-9007","type":"print"},{"value":"1423-0410","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,9,6]]}}}
