Some blood centres require consent from donors to be registered with a national registry. This situation provides an opportunity to determine whether a donor\u2019s willingness to register is associated with a change in donation behaviour.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Rare donors were identified by molecular typing. The average number of donations per year was compared for each donor prior to and after receiving a consent letter. Donors were categorized as either accepting or declining the request. Non\u2010parametric <jats:italic>t<\/jats:italic> tests compared the statistical significance within and between categories. Rare types were overlaid with consensus data to look for trends using data visualization techniques.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 270 molecularly typed rare donors received letters over 4\u00a0years. Half of the donors (132, 49%) agreed to participate in the ARDP. Overall, donation frequency increased after the letter when enrolled. Both Caucasian and non\u2010Caucasian donors increased their donations after enrolling providing an additional 159 red blood cell units over 3\u00a0years. Declining participation did not change donation frequency. Data visualization showed that enrolled donors were more affluent, high school and college educated, and lived in their home for longer periods of time.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A donor\u2019s willingness to enrol in the ARDP was associated with a post\u2010response increase in donation frequency. New interventions to reach non\u2010Caucasian donors may be a prerequisite to increase donation frequency and a willingness to be a rare blood donor.<\/jats:p><\/jats:sec>","DOI":"10.1111\/vox.13047","type":"journal-article","created":{"date-parts":[[2021,1,6]],"date-time":"2021-01-06T07:07:37Z","timestamp":1609916857000},"page":"601-608","source":"Crossref","is-referenced-by-count":2,"title":["Red cell genotyping of rare blood donors: donation behaviour and data visualization"],"prefix":"10.1111","volume":"116","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2715-642X","authenticated-orcid":false,"given":"Waseem Q.","family":"Anani","sequence":"first","affiliation":[{"name":"Diagnostic Laboratories Versiti Milwaukee WI USA"},{"name":"Department of Pathology Medical College of Wisconsin Milwaukee WI USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jerome","family":"Gottschall","sequence":"additional","affiliation":[{"name":"Diagnostic Laboratories Versiti Milwaukee WI USA"},{"name":"Department of Pathology Medical College of Wisconsin Milwaukee WI USA"},{"name":"Blood Research Institute Versiti Milwaukee WI USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8727-1679","authenticated-orcid":false,"given":"Gregory A.","family":"Denomme","sequence":"additional","affiliation":[{"name":"Diagnostic Laboratories Versiti Milwaukee WI USA"},{"name":"Blood Research Institute Versiti Milwaukee WI USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,1,5]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.14376"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1159\/000366149"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrc.2012.02.017"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.2003.00565.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.14611"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tmrv.2018.07.003"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.21307\/immunohematology-2019-048"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.21307\/immunohematology-2019-033"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.21307\/immunohematology-2019-036"},{"key":"e_1_2_6_11_1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.21307\/immunohematology-2019-038","article-title":"The Israeli rare donor blood program","volume":"32","author":"Yahalom V","year":"2016","journal-title":"Immunohematology"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.21307\/immunohematology-2019-049"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.21307\/immunohematology-2019-040"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.21307\/immunohematology-2019-045"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.21307\/immunohematology-2019-037"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1537-2995.2006.00907.x"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.14113"},{"key":"e_1_2_6_18_1","first-page":"517","article-title":"Millennials and volunteering: sector differences and implications for public service motivation theory","volume":"40","author":"Ertas N","year":"2016","journal-title":"Public Adm Quarterly"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1080\/10495142.2014.965069"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1159\/000318023"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/trf.13168"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1537-2995.2009.02570.x"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.5858\/133.9.1444"},{"key":"e_1_2_6_24_1","unstructured":"Bureau USC:American Community Survey 2015 American Community Survey 5\u2010Year Estimates.http:\/\/factfinder.census.gov(Last accessed 1\/27\/2019 2019)."},{"key":"e_1_2_6_25_1","doi-asserted-by":"crossref","first-page":"159","DOI":"10.1007\/978-1-4842-1443-5_10","volume-title":"Power Map for Excel;
