    :redface:Thank you very much, Malcolm. I feel very grateful you post the thread after a long drive and are very tired. And Geoff Daniels is a great man in this field, you can ask my question to him , I feel very lucky.

    Thank you ,Malcolm. Sorry for my English. I can't understand if your meaning is when suspicious of Del the G antigen will be weak in such case as D antigen.

    I am not a physician, so my opinion maybe not right. I have read some books say about CVP, I think this is a indication of infusion and blood loss balance. As to time , I think it is been infected by the blood loss rate. This is just my opinion.

    What is the method? AHG?
  5. Yanxia
    Thank you Malcolm. I look forward to your result. Del can appear in DcE phenotype, but it is very rare, and in Dce is rare too.

    I think the three day frame have a premise which is previous 3 monthes transfusion or pregnancy. If not, the antibody status will not chang except decrease with time. So, I think if the patient has not been transfused or pregnant during the three month and have not been transfused after the day of blood specimen been drawn, the blood crossmatched can be transfued safely in any day of its life span.

    Very good point!

    I have read some paper about Del , it appears more than 90% in r'r phenotype cells. We all know the G antigen, it is the joint antigen of D and C antigen. So, I have a question: Does the Del is in real a G antigen?:)

    Anti-f

    Yanxia replied to Losmeister's topic in Case Studies

    I think it is e and c neg blood that is f neg.

    Anti-f

    Yanxia replied to Losmeister's topic in Case Studies

    I am very happy to see your post Malcolm. One question: What is anti-d, d antigen is not exist,is it true?
  11. Yanxia
    Yes, David is right. And this patient had kidney disease, to expel fluid's function is not good, so this maybe one reason .
  12. Yanxia
    I am suspicious he is TACO.

    AMcCord , sorry for my poor English, would you tell me the meaning of 45 degrees , is it temperature or angle?
  14. Yanxia
    Panda,you are right, HLA antibodies are prevalent with TRALI, but some TRALI the HLA antibodies is neg, as to DAT , I don't think it can different the two. I remember 2009's Transfusion has a paper about the two's differ, it mentioned BNP as AMcCord mentioned. It is a pity I can't provide this paper to you, if someone can help to provid it, it will be welcom.

    David, We had used DiaMed, now we use the gel card make in China.

    Anti-f

    Yanxia replied to Losmeister's topic in Case Studies

    But autoantibody is almost panagglutinate, I don't think there is compatibility between those two kind of anti-f.
  17. Yanxia
    I VOTE FOR TUBE TOO The reason is same as Vic. I don't know the sensitivity difference, but I think we do forward and reverse type in ABO ,so we can find the subtype by it, although the method we use not dest the antigen. As to D antigen, we all know too sensitive is not a good point in receipt.

    Anti-f

    Yanxia replied to Losmeister's topic in Case Studies

    :juggle::juggle:This paper is wonderful, but I find an error in it"Qualitative differences have also been reported with anti-f produced by CdelcDE individuals compared to anti-f produced by cDelcDE individuals" According the author cDelcDE individuals can produce f antigen not anti-f except autoantibody. So I am suspicion about this paper. Malcolm , you are not here many days, are you very busy , can you help us to explain this? Thanks!
  19. Yanxia
    The mom is O postive, why she receive anti-D ?
  20. Yanxia
    I don't think you can report it as a cold antibody. And I find some cold antibodies in get is mix field reaction, but I don't think I can report it as cold just from the gel reaction. Because some thing can show the same reaction like this .
  21. Yanxia
    I remember in the 15th edition of AABB technical manual about ABO subtype detection said that we use IS first then AHG to confirm the weak A or B antigens. I think this can prove AHG can detect A or B reaction and it is more sensitive than IS.
  22. Yanxia
    Me, too.
  23. Yanxia
    Me too.

    I wonder is there someone find the elution positive and DAT neg patient , what ablut their DAT check microscopically. I think this is a question about workflow, if we suspect hemolysis reaction we check the DAT , macroscopically, then elution we can find the binding antibodies below detect level; microscopically, maybe we can find the weak reaction , what is next , elution,too.
  25. Yanxia
    Thanks rravkin@aol.com , I agree totally with you, my previous post is somewhat garble quote out of context.
