I specifically remember doing the Lui freeze -thaw on DAT + ABO incompatible cords samples in 81' at the Blood Bank in Bethesda MD so possibly the name and method predated the article.   

That is very said news.  He was a great leader in Transfusion Medicine.  We all have fond memories of him.  As a Navy SBB Fellow, we would attend the Univ of Michigan seminars and John Judd would spend time talking with us about different issues we had at our medical centers.  He really gave a personal touch that was greatly appreciated.  He will definitely be missed.   

Not sure about just one answer - We had a labeled Rh negative RBC from the ARC that retyped as Rh positive.  Upon investigation, it was found the Immucor anti-D reagent we use for retyping had anti-Crawford while the ARC automated process for D typing used an Ortho reagent which was from a different clone.  Not very unlikely but certainly more than one answer.    

I concur! This was a great symposium.  The SBB program I attended sent us to Ann Arbor in 97' and I arranged to go back nearly every year up to 2013 or 2014.  We came away with new ideas and confidence in our job.   Plus, the Weber Inn was a great place to stay.  On the down side listening to John Judd talk about warm beer was not fun.  Beer should be drunk ice cold.

A number of years ago the President made a visit to our area.  His advance team visited our hospital and the blood bank.  They asked if we were AABB accredited which we regrettably answered no.  We are accredited by the Joint Commission   Consequently our blood bank was told we could not provide blood product in the event of a medical emergency!

You use a less sensitive assay method to reduce interference with cold and warm auto antibodies that you have shown or proven are not clinically significant, with the idea that a clinically significant allo antibody like Kell, if present, will shine through.  It's a balancing act.  

A closed system room temp product expires in 6 hours.  An open system room temp blood product expires in 4 hours.  In most cases the blood product, ie RBC unit, doesn't become an open system until it is spiked.  If your policy is to start the transfusion within 30 to 60 minutes from issue, then you would still comply with the regulations if the total time of the transfusion, from spike to completion is no longer than 4 hours. The 4 hour time limit is easier to comply when the RN is keeping track of the time it starts until completion, not when it is issued since that time is likely only documented in the blood bank computer.

I've attached our validation plan that we used last year.  Some of it is Sunquest-specific, but hopefully you find it useful.  You will find more detail regarding Ortho's guidelines in their Validation Manual.  Our plant was to ensure we were doing approximately one week's worth of samples, but we ended up doing a lot more than that to work out some kinks we found during testing and to ensure that we had a good assortment of antibodies and scenarios.

Rh discrepancies caused by variable reactivity of partial and weak D types with different serologic techniquesGregory A. Denomme, Louann R. Dake, Daniel Vilensky, Lily Ramyar, W. John Judd Article first published online: 7 DEC 2007

We use Cerner Millenium.  Although it is not perfect, once you learn the tasks it does the job.  We have clinics that use Epic and are now developing an interface so providers can order blood products.  This is not completed so I can not say one way or another how well it works.  I have used Mysis, Meditech, and DBSS (the military blood system) in the past and so far, Cerner seems to work out the best. I hope that helps.
