About 75% of the population possesses P1 phenotype. P2 simply implies P1 negative and there is no P2 antigen. Individuals with P2 may have anti-P1 antibodies in there serum are cold-reacting antibodies which are clinically insignificant and occasionally active at 20\u00b0C or higher temperatures. However, in certain cases, anti-P1 is clinically significant and may cause acute intravascular hemolytic transfusion reactions. Our case report confirms the complexity and difficulty in the diagnosis of anti-P1. In India, very few cases are reported regarding clinical significant anti-P1. Here, we report a case of IgM type of antibody anti-P1 which was reactive at 37\u00b0C and AHG phase in a 66-year-old female planned for Whipple's surgery, who had grouping discrepancies in reverse typing and incompatibility during routine crossmatch.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/ajts.ajts_165_21","type":"journal-article","created":{"date-parts":[[2022,9,27]],"date-time":"2022-09-27T04:48:23Z","timestamp":1664254103000},"page":"125-127","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Clinical significant anti-P1 antibody with wide thermal amplitude"],"prefix":"10.4103","volume":"17","author":[{"given":"Nallagondla","family":"Thulasiram","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dibyajyoti","family":"Sahoo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhishekh","family":"Basavarajegowda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-22-20240830","first-page":"1077","article-title":"P1 K: A rare blood group phenotype","volume":"6","author":"Mahesar","year":"2018","journal-title":"J Hematol Transfus"},{"key":"R3-22-20240830","doi-asserted-by":"crossref","first-page":"678","DOI":"10.1182\/blood-2010-08-301333","article-title":"Identification of a novel A4GALT exon reveals the genetic basis of the P1\/P2 histo-blood groups","volume":"117","author":"Thuresson","year":"2011","journal-title":"Blood"},{"key":"R4-22-20240830","doi-asserted-by":"crossref","first-page":"380","DOI":"10.1159\/000490897","article-title":"Acute hemolytic transfusion reaction due to anti-P1: A case report and review of institutional experience","volume":"46","author":"Smith","year":"2019","journal-title":"Transfus Med Hemother"},{"key":"R5-22-20240830","doi-asserted-by":"crossref","first-page":"769","DOI":"10.1111\/j.1699-0463.1949.tb00781.x","article-title":"On the heredity of blood factor P","volume":"26","author":"Henningsen","year":"1949","journal-title":"Acta Pathol Microbiol Scand"},{"key":"R6-22-20240830","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1111\/j.1365-2141.1958.tb03843.x","article-title":"Relation between characteristics of blood-group antibodies in vitro and associated patterns of redcell destruction in vivo","volume":"4","author":"Cutbush","year":"1958","journal-title":"Br J Haematol"},{"key":"R7-22-20240830","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1002\/ajh.20264","article-title":"Acute hemolytic transfusion reaction by anti-P1 antibody in pregnancy","volume":"78","author":"Thakral","year":"2005","journal-title":"Am J Hematol"},{"key":"R8-22-20240830","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1046\/j.1537-2995.1998.38498257376.x","article-title":"An acute hemolytic transfusion reaction caused by an anti-P1 that reacted at 37 degrees C","volume":"38","author":"Arndt","year":"1998","journal-title":"Transfusion"},{"key":"R9-22-20240830","first-page":"383","article-title":"Hemolytic transfusion reaction caused by IgG anti-P1","volume":"18","author":"DiNapoli","year":"1978","journal-title":"Transfusion"}],"container-title":["Asian Journal of Transfusion Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ajts.ajts_165_21","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T15:14:50Z","timestamp":1787757290000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ajts.ajts_165_21"}},"subtitle":["A tale of successful blood management"],"short-title":[],"issued":{"date-parts":[[2023,1]]},"references-count":8,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2023]]}},"URL":"https:\/\/doi.org\/10.4103\/ajts.ajts_165_21","relation":{},"ISSN":["0973-6247"],"issn-type":[{"value":"0973-6247","type":"print"}],"subject":[],"published":{"date-parts":[[2023,1]]}}}
