  1. I agree that the difference between cisAB and B (A) is serological and divergent. They coulding be one, but they respect the names given by the authors. I do not think that the ABO * cisAB.05 and ABO * BA.06 alleles are different. It must have been an ISBT mistake! See a summary I made in 2019. In general, the phenotype cisAB presents normal expression of antigen A, but similarly to phenotype A2, and weak expression of antigen B. On the other hand, B(A) presents a very weak expression of antigen A, but a normal expression of B.(1) The rare phenotype cisAB was first described in a
  2. Hi, What barrier method are you using to ensure that the blood bag reaches the correct patient? I am researching to update and increase security in the service I work for. I appreciate all the contribution,
  3. I would like to know the behaviors that have been adopted in your service in cases of bone marrow transplantation from RhD + patient, RhD- donor for transfusion of platelet concentrate. Is there a concern to provide RhD- since the infusion? Or after the patient only presents donor phenotyping RhD-? In the impossibility of providing RhD-, have hemotherapists indicated anti-D prophylaxis?
  4. We understand what happened. We received the patient 12 hours before this transfusion. Despite having denied previous transfusions, we contacted the health service of origin who informed us that he had transfused platelets in pool (600 ML) the group O. Therefore, we believe that the reaction after red blood cell transfusion was a coincidence, and the anti-B of the transfused platelets must be the cause of hemolysis.
  5. We performed the tests with serum, everything negative. The most likely suspicion is passive anti-B
  6. Thank you Malcolm, we do not test with serum, I will do the tests now
  7. Hello, I need help to understand this Acute Transfusional Hemolytic Reaction. A patient under investigation for acute promyelocytic leukemia, after transfusion of red blood cells in group O, presented fever (38.6 ° C). Immunohematological results of the patient: - pre-transfusion: B negative, negative irregular antibody test, negative DAT, negative compatibility test - post-transfusion: negative B, negative IAT, positive DAT 2+ (C3d only), negative compatibility test, negative eluate, negative anti-B test with eluate serum Laboratory results: - evidence of hemolysis: DA
  8. I do not agree with the transfusion prescribed at pre-defined frequencies, such as 4/4, 6/6, 8/8 and 12/12 hours. We are trying to change this here, but we find resistance. How is it in your service?
  9. Thank you all for the answers. Unfortunately, some places here in Brazil employ nursing technicians to work in a blood bank.
  10. Sorry Malcolm, I did not get it. Is it better to have nothing than to leave them to do? Or simply is a bad option!
  11. We have already thought about releasing red blood cells from group O until a confirmation, but it was not well accepted at the time. Do you have problems with stock due to red blood cell release "O" until confirmation? How do you do for underweight children? Do you wash the red blood cells to remove antibodies?
  12. Yes, in Brazil too, but not for an additional test at the bedside. Either way, training is needed also.
