Thank you Malcolm, I will check out that reference!

Thank you Malcolm Needs! Do you know of any reference books that can attest to this that I can show my higher ups? About a year ago we started reporting positive DAT “possibly due to RHIG” if baby is Rh Pos and mom received RHIG in the last 3 months, even if her screen is neg. My Medical Director and QA are now telling me that this isn’t possible and that we need to be repeating screen on mom if baby has positive DAT, but mom has neg screen (received RHIG in last 3 months and is ABO compatible). I want my SOPs to be accurate, but I also don’t want to overdo it. On the subject of not doing the DATs, I would be happy to get rid of the DATs on babies, but we are about to implement the Ortho Vision, and I’m not sure how to do a cord without the DAT. The cord is run on the ABD Forward and Rev card and the only way that I can figure out to program this card without the reverse type is to do it with the DAT. If you or anyone else knows how to program this and is willing to share, it would be greatly appreciated! On the topic of getting rid of the DATs, if the baby is weak D positive, are you then doing the DAT to confirm the validity of the weak D result? Thank you for all of your expertise!

Good afternoon, has anyone else seen positive DATs on cords when baby is Rh positive and mother has received RHIG antenatally, but on admission for delivery has negative antibody screen? We have seen this on numerous occasions, but it is currently being called into question. Is it safe to presume the DAT is positive due to RHIG or should we repeat the DAT on cord and screen on mom when this happens? Is there a reason why the cord DAT would be more sensitive than the antibody screen? We do all tube testing and use LISS as our enhancement. Thank you!

Hello, Is anyone out there using low titer group O Whole blood for patients? We are on track to use it for trauma patients in the near future. Any information you can share about your process would be extremely helpful. A couple questions I have right now: Can you run Whole blood through a blood warmer/rapid infuser? Seems like a no-brainer since it will be used for trauma patients, but you don't run platelets through a blood warmer, and that's one of the pluses of Whole blood is that there are activated platelets present. How do you cross match Whole blood? I vaguely remember learning about Whole blood crossmatches in school, but we were told we would never use Whole blood in real life do you XM the patient's plasma with the donor cells, the the donor plasma with the patient cells? Since it will all be group O blood, wouldn't we expect the plasma to be incompatible with out of group RBCs, even I found it is low titer? Is there any benefit to the crossmatch if we know it will be incompatible, and we know low titer group O is safe for non-group O patients? Can we expect discrepancies in the reverse blood type of non-group O patients if blood is collected after Whole blood has been given? How much Whole blood before we can expect a discrepancy? Can you switch to type specific packed RBCs after giving Whole blood? I understand that bleeding patient will be bleeding out the anti-A and Anti-B from the group O plasma, but what happens Hohenzollern the patient stops bleeding, still has Whole blood in circulation Andy then you give type specific blood that will be hanging out with those antibodies for the next few weeks/months? Should we expect hemolysis? What limits did you set on the use of Whole blood? Only for certain diagnoses (just trauma? What about other massive bleeding like GI bleed, ruptured/perforated AAAs, post partum hemorrhage?)? Only in certain areas of hospital (just in ED/OR)? Is there an age limit/range? Is there a weight/size range/limit (specifically is it ok for smaller people)? Not available for people with specific conditions (CHF)? How did you educate medical/clinical staff? Any good resources you are willing to share? Any issues encountered in Transfusion Services (BECS? Tech training/understanding? Things you wished you'd have known when you started using Whole blood or lessons learned along the way?) What is the max number of low titer group O whole blood units you will give a patient? How much do you maintain in inventory? How much is used vs. wasted? If you are willing to share any processes or procedures, it would be greatly appreciated! Thank you!

We use a Fluke 561 IR thermometer for temps on our blood products. We send it for calibration annually and test it monthly against a NIST thermometer at freezer temp (-28 to -30C), refrigerator temp (about 4C), room temp (21-22C), and thaw bath temp (35-37C) . We wrap a unit at the specified temp around a NIST thermometer long enough for it to equillibrate, then hit it with the IR thermometer. It always correlates within 1C of the NIST, except at freezer temps, which is a little further from 1C. We don't use it to take the temperature of anything in the freezer, but there may come a time where that is useful. I hope this helps
