  1. Antigen Tested Units

    We test if the patient already has the antibody. We've had units come in that were marked one thing but were actually the opposite.
  2. Rule out Anti-K

    I remember from somewhere that Kell doesn't or is least likely to show dosage.
  3. Going into the bag with a needle would make it an open system. Does the bag not have segments attached?
  4. 2rd determination of recipient's ABO

    We either get a sample from Hematology or have a second sample drawn. Retesting the same sample twice does not rule out pre-analytical errors.
  5. I remember that too, but this was a gas I think. It left a residue in the disposables that caused some patients to go into anaphylactic shock. It was in the Technical Manual a few versions back.
  6. I vaguely remember hearing that patients may react to the chemical used to sterilize plastics. I think it's a bigger problem with patients on dialysis.
  7. M antigen and antibody

    Children frequently make anti-M that reacts at Coombs phase. This is usually without known sensitization. I saw this in a text book years ago, but have seen it in real life many times during my 36 years of pediatric blood banking.
  8. CAP Alternative Assessments-Help!

    We use API. It is cheaper but you don't have as much time to do them.
  9. In pediatrics we often struggle to get an adequate sample, so most of the time we go directly to the panel.
  10. I was wondering if Amy is a blood banker.
  11. 2 Mysteries

    Never mind. I just read it again.
  12. 2 Mysteries

    Unless I'm missing something, the first case could be caused by maternal anti-B.
  13. Antibody Titers Gel vs. Tube

    I think Johns Hopkins does titres in gel. We looked at it a few years ago for our isohemagglutinin titres, but decided to stay with tubes.
  14. We don't titre because we don't have anything to do with the mother's care, but I know the hospital down the street tracks the titre. As for the panel/screen, I take the antigen profile and circle all the required antigens. Then I select a cell that is homozygous for each one. I sometimes have to use cells from other panels or screens. I know the rule is that you can substitute two heterozygous cells for one homozygous cell, but I never do that if I can help it.
  15. If you know she has anti-E, you can probably put together a custom screen of E negative cells. That screen would only be positive if she developed another antibody. Be careful that you cover all the antigens that the FDA requires. That list used to be in the Technical Manual. I think it is D, C, E, c, e, M, N, S, s, P1, Lea, Leb, K, k, Fya, Fyb, Jka, Jkb.
