There are a variety of methods for washing red cells, and the laboratory data suggest that variables such as age of red cell before washing, washing method and solution, storage medium and length of storage time after washing can all effect the final red cell quality. Studies suggest that washing removes 90\u201395% plasma, but the proportion of units below 0\u00b705\u00a0mg\/dl IgA (equivalent to IgA deficient) is variable dependent upon methods used. Although potassium levels are reduced immediately following washing, the rate of leakage following subsequent storage is method\u2010dependent, requiring careful consideration of shelf life if potassium reduction is the goal. Other markers of red cell quality such as haemolysis are negatively impacted by washing so a reduced shelf life compared to standard red cells is appropriate, especially following irradiation. Data from animal models and clinical studies on possible additional benefits of washing, such as reduced lung or kidney injury, are mixed, ranging from some benefit to some harm, and further studies are warranted.<\/jats:p>","DOI":"10.1111\/vox.12971","type":"journal-article","created":{"date-parts":[[2020,7,7]],"date-time":"2020-07-07T12:13:20Z","timestamp":1594124000000},"page":"606-616","source":"Crossref","is-referenced-by-count":36,"title":["Washed red cells: theory and practice"],"prefix":"10.1111","volume":"115","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6823-8937","authenticated-orcid":false,"given":"Rebecca","family":"Cardigan","sequence":"first","affiliation":[{"name":"Department of Haematology NHS Blood &amp; Transplant University of Cambridge Cambridge UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helen V.","family":"New","sequence":"additional","affiliation":[{"name":"Department of Haematology NHS Blood &amp; Transplant Imperial College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hazel","family":"Tinegate","sequence":"additional","affiliation":[{"name":"NHS Blood &amp; Transplant Newcastle UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Thomas","sequence":"additional","affiliation":[{"name":"NHS Blood &amp; Transplant London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,7,7]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjh.12017"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejcts.2007.01.014"},{"key":"e_1_2_10_4_1","unstructured":"Canadian Blood Services.Clinical Guide to Transfusion: Adverse Reactions[Internet].
