The Sue Johnson knowledge bomb continues as she shows us how to choose compatible blood products and TEST them to make sure they are compatible. Don’t miss this episode of the Blood Bank Guy Essentials Podcast! [NOTE: Previously titled, “Pretransfusion Testing 1”]
The Last Three Steps of Pretransfusion Testing
Sue starts this interview with a discussion of how you use the information gained in step 2 (the patient’s ABO, Rh, and unexpected antibody status) to choose the best and hopefully most compatible product for a blood recipient. She shares tips and tricks to best practice in choosing red blood cells, plasma, and platelets. Then, she takes us through the ins and outs of compatibility testing (the test we all call the “crossmatch”), including a nuts and bolts description of both forms of the serologic crossmatch (Immediate-spin and AHG). She describes the computer (or “electronic”) crossmatch, and tells us why she thinks it is the very BEST crossmatch you can do! Finally, Sue briefly describes some labeling requirements.
But Wait, There’s MORE!
In the last half of this interview, I hit Sue with six cases designed to illustrate some of the more common challenges that we encounter in compatibility testing, and Sue handled them like a pro! Don’t miss the chance to hear a master at work, showing you exactly how to handle unexpected findings either in the crossmatch itself or with other tests related to the crossmatch.
