I believe that the 2004 CAP checklist has a note associated with this checklist item that says "Records of specific reactivity checks for A cells, B cells, anti-A and anti-B may be omitted when forward and reverse grouping results consistently agree." I don't know if there is a 2005 checklist version, but this note has been in several previous versions. I'm at a blood center that is not CAP-accredited but I got this information from their website.
