Transfusion of Uncrossmatched Group O Erythrocyte-containing Products Does Not Interfere with Most ABO Typings

Conclusions The transfusion of smaller quantities of uncrossmatched type O erythrocyte-containing products, in particular up to 10 units, does not usually interfere with determining the recipient ’s ABO type. The early collection of a type and screen sample is important.Editor ’s PerspectiveWhat We Already Know about This TopicUncrossmatched erythrocyte units that are provided to a massively bleeding patient whose ABO group is unknown must be type O to ensure compatibility. The effect of transfusing type O units on the ability to subsequently determine the patient ’s ABO group is not known.What This Article Tells Us That Is NewABO typing in 665 of 695 (95.7%) non –group O recipients could be accurately determined on the first type and screen sample obtained by the blood bank after the transfusion of uncrossmatched type O erythrocyte-containing products.
