  1. Just my guess, is there any possibilities of fetus D pos cells bind partof the antibodies?
  2. We have encountered a patient who produced auto anti-A(or A1,sorry I didn't identify it).
  3. Sorry,I can't find the English version.The underlined sentence means the cord blood cells needed to be washed at least once before testing.
  4. I am so lazy that I just checked our IgG card today . I noticed it said that cord blood need to be washed before testing. I am at home now, I will attach the package insert tomorrow.
  5. I guess this may be caused by the Wharton's Jelly which can cause rouleaux formation of the cord cells. For the gel technique, it is good to test the adult cells without washing, but for the cord cells, maybe the Wharton's Jelly block antigens on the cells' surface. I noticed that patients suffer from Multiple myeloma will not show false positive reaction in gel, but saddly I have not confirmed if there are false negative reactons.
  6. I prefer the each individual one policy. Because we can not make sure the baby has the combined antigens.
  7. Thanks for your sharing, Malcolm. In the course of reading the cases above, I encountered many problems which resolved by checking on books. This is a very impressive way to absorb new knowledge. As a hospital blood bank worker, I rarely have chances to get access to thoes cases.
  8. Here is a follow up. The baby had tested with anti-A on 27, April and transfused with O washed cells the same day, but on 10, May she had no anti-A and received A type packed red cells with no transfusion reaction. She has stoped feeding on her mother's milk for 14 days. I tried to persuade her mother to do some tests. The results came out and she has no anemia, with normal reticulocyte count and percentage. Her bilirubin and LDH are normal too. But she has not tested her haptoglobin. She has not received any blood transfusion and IVIG. She just diagnosed with slight anemia during pregnancy and after birth. She had taken iron supplements during pregnancy,. This is her eventh pregnancies and the third baby, she had several miscarriages. She told me her case seems like a mystery both to her and the doctors she know. She just want to know if she is ok and the baby will be healthy in the future.
  9. The baby is discharged now, we cannot test the mother anymore, what a pity.
  10. She is still breast feeding the baby, and looks healthy.
  11. Thank you very much, Arno. Only one question left, why does the mom asymptomatic even with auto anti-A. We have encountered another case of auto anti-A, that one need transfusion.
  12. Thanks, Malcom. 1. I am not sure it is.anti-A, not.anti-A1. I mathed 5 A donors with the patient and the reactions.are all positive(Maybe they all A1). It is my fault, I need to add A2 cells to make sure about it. 2. I searched about the FORS1 online, there are few papers I can find. I will try my books tomorrow. This.is the.first time I read this antigen. Is there any cross reaction between it and A( or A1) antigen? 3. There is an idea just poped on my mind, it maybe Tn. But I don't know if Tn can give so strong reaction with monoconal anti-A reagent.
  13. No, He has got nothing above. I guess the antobodies come from the mom, maybe from breast breeding , but have not heard about it before. Will the milk origined anotibodies come into the blood stream and be IgG?
  14. Thanks, sbbguy. At first I thought maybe the mom is A2 type, too. But she is A1 type with pos DAT due to IgG. I feel so confused.
