  1. Return of used blood

    Our only difference was that we cut off 2 segments. We stopped getting bags back over 25 years ago. Hated the mess and getting them back served no real purpose.
  2. Gel and tube discrepancy in antibody screen

    Just to make sure I understand, this was done as comparison between 2 methods in use and you do this every 6 months. How many samples do you compare?
  3. Gel and tube discrepancy in antibody screen

    I'm just curious, why are you doing both tube and gel on the same patient/donor? Do you do it on every patient/donor or was this a special case for some reason?
  4. can we use hemolysis sample to prepare blood units ?

    Just as a side note, most of the hemolysis I saw was in tubes that were collected by a nurse when they started an IV. Not sure what the exact correlation was but that was the case more often than not.
  5. Eluates on babies with positive DATs

    Just to clarify, at this point in the discussion I was referring to a positive DAT obviously (most likely) due to an ABO incompatibility between mom and baby.
  6. Eluates on babies with positive DATs

    My question is when was the most current antibody screen performed, just prior to the RhIG injection or just prior to the delivery, or after the delivery? Also, as I think about it, was an elution performed at the time of the positive DAT? One more thought, if the antibody screen was performed just prior to or just after delivery most of the available antibody could be attached to the babies cells resulting in a negative antibody screen.
  7. FDA reportable events

    Cliff, I'm glad to hear things have improved since the last time I submitted anything to them many years ago. I remember my first FDA inspector had just came from a meat packing plant and the only thing he knew about blood banks was his check list. The last one I had was actually an SBB. I was excited to see they were making an effort to do it right.
  8. FDA reportable events

    Ann, on the flip side I bet there is a lot that gets reported that doesn't need to be reported for fear of getting caught not reporting something. Unless the FDA has improved their information in the past few years, a lot of what they say leaves a great deal of room for interpretation.
  9. Can leuko-reduce prevent GVHD

    Well Neil, it looks like a lot of folks may be dragging their old IBM 2991 cell washers out and dusting them off. Great information, thanks.
  10. CAP TRM. 40670

    Malcolm, you make me laugh. Just like a bull dog, once you get hold of something you just can't let go. I think the moto from a place I once worked is appropriate. "An exercise in futility is better than no exercise at all!"
  11. Amount of plasma removal for Exchange Transfusion?

    Good luck with the exchange. The worst case of HDN I ever saw was caused by anti-c.
  12. Amount of plasma removal for Exchange Transfusion?

    To questions just out of idle curiosity. What's the antibody and where on earth are you getting whole blood?
  13. I'm confused here. Isn't placental blood mom's blood? I guess it depends on which side you get it but then the other side is cord blood so why would anyone want to use placental blood for pretransfusion testing? What am I missing here?
  14. AABB 5.15.4 (European input welcome)

    I've put off weighing in on this topic for as long as I can. I really hate impossible "shall have" rules and regulations. First you would need to know/calculate the body mass/blood volume of the patient. Then you would need know the level of activity of the incompatible ABO antibodies in each unit of plasma going into that patient. Then you would need to know the volume they are bleeding it back out. All this to give you an accurate estimate of the volume of incompatible plasma you could "safely" give one specific patient. I'm sure I've left out a factor or two but you get the gist of what I'm saying. My minor level of OCD really whats me to do it right if I'm going to do it at all. I had a non-technical lab director (BA in business) throw me out of his office for trying to explain why the request for certain data by a VP was not only impossible to accurately provide but was a stupid, worthless waste of time. This is one of those times where you and your lab director will have to make something up based on your best guess and basic instincts because there is no one size fits all answer to this.
  15. Quarterly Alarm Checks

    Since I'm relatively lazy I remember doing just the electronic checks once we had units that had that as an option. I don't recall ever having an issue with an inspection. I think it goes back to the old matra of "follow the manufacture's directions grasshopper" and I don't recall Helmer recommending the old ice water trick.
