These subgroups show weaker and variable serologic reactivity with the commonly used human polyclonal antisera, thus causing group discrepancy and dilemma to resolve these problems and mismatch blood transfusion. Here, we present a case of weak B subgroup detected in a 40-year-old male voluntary blood donor. His red cells showed weak agglutination with anti-B and anti-AB, and in his serum, there were potent anti-A and weak anti-B which were not detected at 37\u00b0C. After adsorption with anti-B, an eluate was prepared from the patient\u2019s cells which agglutinate with B and AB cells but did not agglutinate with A or O cells. His probable blood group is Bx. With special serological testing, a rare group is detected and decision is made to provide blood to the right patient at the right time.<\/jats:p>","DOI":"10.4103\/ajts.ajts_21_21","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T02:43:12Z","timestamp":1653964992000},"page":"138-140","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Resolution of blood group discrepancy and serological evaluation of weak B phenotype in a healthy blood donor: A case report from West Bengal"],"prefix":"10.4103","volume":"19","author":[{"given":"Sourav","family":"Mukherjee","sequence":"first","affiliation":[{"name":"Department of Transfusion Medicine and Blood Centre, Peerless Hospital, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anuja Ghosh","family":"Dastidar","sequence":"additional","affiliation":[{"name":"Department of Transfusion Medicine and Blood Centre, Peerless Hospital, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vikash","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Transfusion Medicine and Blood Centre, Peerless Hospital, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Purushottam","family":"Chatterjee","sequence":"additional","affiliation":[{"name":"Department of Transfusion Medicine and Blood Centre, Peerless Hospital, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,5,26]]},"reference":[{"key":"R1-20260422","doi-asserted-by":"crossref","first-page":"565","DOI":"10.1016\/S0300-9084(01)01321-9","article-title":"ABH and Lewis histo-blood group antigens, a model for the meaning of oligosaccharide diversity in the face of a changing world","volume":"83","author":"Marionneau","year":"2001","journal-title":"Biochimie"},{"key":"R2-20260422","doi-asserted-by":"crossref","first-page":"2442","DOI":"10.1111\/j.1537-2995.2008.01878.x","article-title":"Molecular genetic analysis for the B subgroup revealing two novel alleles in the ABO gene","volume":"48","author":"Cai","year":"2008","journal-title":"Transfusion"},{"key":"R6-20260422","doi-asserted-by":"crossref","first-page":"864","DOI":"10.1111\/j.1537-2995.2007.01203.x","article-title":"Structural basis for red cell phenotypic changes in newly identified, naturally occurring subgroup mutants of the human blood group B glycosyltransferase","volume":"47","author":"Hosseini-Maaf","year":"2007","journal-title":"Transfusion"},{"key":"R7-20260422","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1046\/j.1365-3148.2001.00321.x","article-title":"The ABO blood group system: Historical background","volume":"11","author":"Watkins","year":"2001","journal-title":"Transfus Med"},{"key":"R8-20260422","doi-asserted-by":"crossref","first-page":"628","DOI":"10.1007\/s12288-017-0788-x","article-title":"Discrepancy in blood grouping: subgroups of B-challenges and dilemma","volume":"33","author":"Chaurasia","year":"2017","journal-title":"Indian J Hematol Blood Transfus"}],"container-title":["Asian Journal of Transfusion Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ajts.ajts_21_21","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T18:55:57Z","timestamp":1786647357000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ajts.ajts_21_21"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,5,26]]},"references-count":5,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.4103\/ajts.ajts_21_21","relation":{},"ISSN":["0973-6247","1998-3565"],"issn-type":[{"value":"0973-6247","type":"print"},{"value":"1998-3565","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,5,26]]},"assertion":[{"value":"2021-02-11","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-05-02","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
