Hi everyone, The SOP at my facility considers collection date as day 1 and clot expires day 3 at 23:59,if needed may extend to 11am(magictime) the following day. Then there's the 7 day clot for NPOTs to expire 2 days after surgery or on 6th day-extend to 7days if needed,depending on transfusion status.HCLL has an override option for 3rd day extension at time of issue. I have seen antibodies appear in 16 hours of transfusion from a patient whose band was cutoff,educational mishap.I look at the sample amount and if transfused with prbc's and don't do favors,follow your protocol.There is always emergency release-or 35 minute wait. Thanks,
