  1. Malcolm Needs

    Gold Medal.

    I am enormously honoured to announce that I am going to be awarded the Gold Medal of the British Blood Transfusion Society at their Annual Scientific Meeting in Brighton this year. It is awarded to an individual for their exceptional and long standing services to the Society and to the practice of blood transfusion in the UK. Sorry if this sounds egocentric, but I am very excited.

  2. Malcolm, I meant that statement not as a criticism of them but just a recognition of reality. Frankly I was excited to get the forms back most of the time and fully understood the pressure they were under. When I was in school I worked in the emergency room on night shift so I was very familiar with trauma situations and fully understood the, "do it now and worry about the paperwork later" mentality.

  3. Also, fetal bleed screen testing on a spun sample. Those giant fetal cells will be on top. Mix well before testing!

  4. I can fully understand what you are saying (and agree almost 100%), but I do have some sympathy for them signing the forms "after the event" as it were, because when they do have to use the uncrossmatched blood that quickly, then they are going to be pretty busy doing things like preventing the demise of the patient - if you see what I mean!!!!!!!!!

  5. What I noticed over the years was that many times when faced with signing for uncrossmatched blood the physician would take a second to reevaluate the situation. Often they would then respond with something like, I want it crossmatched so hurry. Not always but it was not uncommon or rare. When they did sign the form it was most often when the crisis had resolved and the dust settled.

  6. Well, that's got rid of two of my possible theories in one fell swoop! I was wondering either about loss of antigenicity due to some form of myeloid malignancy, or of adsorption of autologous secreted A substance on to the donor group O red cell surface following a successful BMT or stem cell transplant, which may be seen with only some clones of anti-A (see, for example, Cripps K, Mullanfiroze K, Hill A, Moss R, Kricke S. Prevalence of adsorbed A antigen onto donor-derived group O red cells in children following stem cell transplantation: A single-centre evaluation. Vox Sang 2023; 118: 153-159. DOI.10.1111/vox.13386., but I saw this phenomenon in adults many times when working at Westminster Hospital). Oh well, back to having more thoughts!
