When I was on bench, which very sadly I am not now, when a patient was transfused with 10 units of PRBC within a 24 hour period, we required a new specimen be obtained and used for any additional crossmatches. I know Standards says a Blood Bank/Transfusion service needs to have a policy regarding compatibility testing when a patient has received, within 24 hours, an amount of blood approximating total blood volume and states no other requirement. Before I update the policy here, I'd like to get an idea of policies/thoughts from fellow BBers. Thanks!
