  1. KBs are performed in our Hematology Department. This test is not uncommon as it is run for more reasons than just to figure out RhIG dosage. I believe, because of this and their more acute training/experience in microscopy, this is the best place for this test to be done. Competency for KB belongs to the section who is performing the test no matter what anyone else uses those results for. The only 'competency' determination that I believe is necessary for the Blood Bank is to assure that the BB Tech who is processing RhIG orders knows how to acquire the KB result and how to calcula
  2. We have been using an Erytra Eflexis (Grifols) for almost 2 years now and we are very happy with it and the service team. It is interfaced to Sunquest.
  3. I agree ... but, unfortunately, along comes that occasional inspector who doesn't see it that way.
  4. I'm chuckling reading all of this because it's like the question, 'If the parents are both Group O, can they produce a Group A baby?' Ask a student, they'll say 'No way!'. Ask a BB fanatic, they'll say, 'Sure it could happen ... and here's how ...' And in this forum, there is never a simple answer!
  5. I'm also wondering how one manages to validate that all units of blood remain within temperature range when the ambient temperature and handling is not consistent. We can't even validate our coolers for the same reason ... and one never knows if the cooler is left open or the units are removed then replaced. Are you using 1-10oC or 1-6oC? FDA instructed us to use 1-6oC for the coolers because they are really 'in storage'. If not in a cooler, we can go up to 10oC because they are 'in transit'. I haven't implemented that part yet, but I will be soon.
  6. Yes: Positive Antibody Screen and Positive DAT.
  7. When we first started using Gel, my techs would point out the shadows or 'jumpies' as they called them. I'd suggest 'Run the screen again using maxtime.' If they still saw the shadows, I'd just let them run a panel (maxtime) and go crazy with the results. After a while we all learned to ignore those reactions. Keep in mind, there are always a certain percent of any given cell population (especially stored reagent cells) that are just not going to make it smoothly to the very bottom solely because of steric hindrance (broken, aged, crenated, tagged for destruction, etc.).
  8. We only use the microscope to check for rouleaux if/when rouleaux is possible/suspected ... and that wouldn't be the case in the AHG Phase.
  9. Of course, all this may be a moot point because at this time, it is highly unlikely that anyone in the US will have an 'overstock' of vaccine. Due to failures and incompetency I don't need to mention, we will be lucky to get a fraction of what we need just to protect our 'front line'.
  10. Congratulations, Malcolm! "For he's a jolly good fellow ... that nobody can deny!' ... so the song goes!
  11. All Blood Products: We require a current BB sample, tested, etc. Plasma, Platelets, Cryo: No time limitation as long as the patient is still wearing the matching BB Band. Plasma: If there is no current sample tested, it is given 'Uncrossmatched'. If I'm interpreting the 'rules' correctly, that's what we have to do for plasma. Platelets: We stock Group A Platelets so that is what they get. We obtain Group compatible if we have to order platelets for a specific patient or a neonate. Shortest outdate is used first. Cryo: There is no consideration for ABO Group ... shortes
  12. We change all batteries annually while we are doing the QA on them so it's not likely that a battery will fail during the year. However, things do happen and I agree with exlimely, if you do have to change or replace (say it fell out for some reason) a battery, then a 'calibration' would be prudent. Also, we are not talking high precision here, i.e. wider acceptability range than a pipette would be, i.e. testing is done in ranges of time, not exact seconds. This 'calibration' is just a simple check up to make sure the timer isn't totally out of range. Most of the time, the error is the
  13. There are actually 2 scenarios in this string: 1. Issuing plasma that you know is incompatible with a patient (i.e. ABO is verified) and 2. Issuing plasma when you haven't verified the patient's ABO with a current sample. For #1: If you are in the US, the CDC/FDA wants us to treat all incompatible plasma as if it were 'Emergency Release' so use your Emergency Release Protocol. For #2: If your patient's ABO Group has not been verified (e.g. sample tested using your protocol for verification), use your Emergency Release Protocol.
  14. We have found that washing the cells 3x with 37C saline will resolve this situation in just about every case where RT Saline wash doesn't help. If you are using Gel, there may be other reasons for the extraneous 'positive results' using your patient cells, e.g. sickled cells, acanthrocytes, protein coating. So, those must also be considered.
  15. We validated using Anti-C3 in a Neutral Gel card.
