    Thanks Bob,for the NEW information.

    Whilst fever or rigors are not uncommon in response to a transfusion and may represent a non-haemolytic febrile reaction, they may also be the first sign of a severe adverse reaction. The transfusion can only be continued if the only feature is a rise in temperature of <1.5oC from baseline or urticaria, recheck that the correct blood is being transfused, give paracetamol and anti-histamine, reset the transfusion at a slower rate and observe more frequently.

    1- Was the patient in October at the time of sample collection dehydrated? 2- Did the patient between October to 12 days later receive any infusions that would have caused dilution of ABT? 3- Furthermore,Technical factors must NOT be over looked such as: a - Phenotype of cells used in the Titrations----? same ! b - Technical skill of technologist if not by same technologist. c - Variations in methods. d - Scoring/ interpreting end point of Titration. I also share with Shily,her concern Why Anti-C titre could be > than Anti-D if it were a case of Anti-G.

    First we use monospecific anti-IgG, anti-C3d with a Contro column, if not helful ;we use monospecific anti-IgG, anti-IgA, anti-IgM, anti-C3c and anti-C3d in a gel card, with a control column.

    Yes,Mr.Melcolm,you are absolutely right, pipetting off a sample of packed red cells through the plasma is safer, We have been doing that since we switch Dia Med (Gel Micro typing system),with NO broblems at all.
  6. Abdulhameed Al-Attas
    We do the same as Mawomack but the Doctor is one who must determine the volume. Also we extend the platelet pheresis (PRP) to two more days beyond their expiry date.

    Congratulations!!!

    I would be grateful if I can have a copy also. attasao@gmail.com

    Same as Galvania, It was a google search for Transfusion in Autoimmune Hemolytic Anemia that made me discover this wonderful site.I am very glad I did !

    Our BB policy is to perform Type,Screen and Dat only once untill 4 month old. If Red cell Transfusion are needed,the Dr.must place the transfusion order,indicating the volume or if Irradiation is required incase of pre-terms. Small volum(Top up)Transfusion is used. 1-Dedicate one unit of fresh (< 5 days from draw date)group O AS-Red cells(RC1) Rh (D) type selected,must be the same as Neonate's. RC1 UNIT SELECTION MUST BE: a-< 5 days old from draw date. b-HBS Screen Negative. c-Not G6PD deficient d-Leukocyte reduced by filtration. e-Irradiated NOT more than 24 hours to time of transfusion. f-Hematocrit 65-85%

    Hi Theresa, We are recording/documenting: Date,Unit #,Component and the Appearance Check-list(Clot,Discoloration,Gas,Leaky and entered) Temperature, action taken:like the Unit was kept for the same patient,Quarantined or made Available & retuned to stock.Also Returned by and the Technologist who recieves back.
  12. Abdulhameed Al-Attas
    I also agree that it is a bad idea, We do Antibody screen on all donors,we do not do Panels if found positive we just discard the unit and related components.

    where is my post gonne?

    where is my post gonne?
  15. Abdulhameed Al-Attas
    I totally agree with Aakupaku, Red blood cells with a positive DAT cann't be testing accuratly with blood typing reagents that require an indirect antigloulin technique unless they have been treated with CHLOROQUINE diphosphate to dissociate IgG from the red cell membrane.
  16. Abdulhameed Al-Attas
    Wellcome to BLOODBANK TALK.
  17. Abdulhameed Al-Attas
    I am afraid I opt to disagree with shily but agree with Rosey. A positive C3d DAT is adequate surrogate indicator of autosensitiztion of the red cells by antibodies whether diseased-induced or otherwise is another issue. Can you give me an example of a disease that causes C3d attachment onto the red cells that is not mediated by antigen-antibody interaction? Thank you.
  18. Abdulhameed Al-Attas
    You are most WELCOME!

    The QUICK Tests usually lack SPECIFISITY,they reac with Any thing that is immunological similar but diagnostically different. It is better to prevent than to creat a medical error.
  20. Abdulhameed Al-Attas
    Three months is the time we keep the segments .
  21. Abdulhameed Al-Attas
    What about your PRE-USE TESTING on the questionable Lot of panels,on receiving day?
  22. Abdulhameed Al-Attas
    The refrigerator you get will be dependent on what standards you want to meet. For example do you want one that would offer electronic traceability of the unit from issue to transfusion? Then you might need to think about HemoSafe. If you are content with just effective blood component storage, protracted maintence-scarce longevity, then obviously you would have to think Forma-Scientific (now Thermo-Scientific) refrigerators/freezers. I have used them for 13 years now, eveyday without breakdown. This is contrary to my experience with Helmer Platelet incubator which broke-down seemingly irreparably within less than 4 years of use whereas its Forma Scientific counterpart has been riding on without breakdown for more than 8 years now. These are facts.

    No. A Donor must not be rejected based on G6PD deficiency. Blood from such donor however may not be used for transfusion of the following patient categories: G6PD deficients, sickle-cell anemics, other hemoglobinopathies, neonates, or surgical patients likely to be subjected to prolonged anaethesia.
  24. Abdulhameed Al-Attas
    NO. It's not iam afraid.Like the sickle cell trait Donors,The worst that could happen is ONLY shortening of the life span of the transfused rbc's. Such Red cell units must be clearly labled so that they will NOT be selected for G6PD and Hemonoglobinopathies patients.But other than that its OK.
  25. Abdulhameed Al-Attas
    What about the option of in house preparation of reagents,Red cells and Antisera. In 2003 during The Iraq war because of delayed delivery,we prepared some Red cell reagents like coomb's check cells(IgG and C3d),and they were wonderful. I don"t think the FDA,CAP and AABB will permit the use of in House Prepared reagents.
