Thanks for your comments. I didn't want to bias any discussion. We are correlating the new BioRad IH500 using the new Diamed cards vs our current Ortho C-D Provue gel cards and there is poor concordance with Kidd antibodies, specifically anti-Jka. The Ortho gel are much more sensitive picking up weak to 2+ reactions while the IH500 gel is showing negative reactions. Anyone have any history or experience with Kidd antibodies on the BioRad Diamed cards specifically?
We are not seeing an evening out of antibody strengths between the 2 cards. Do you think it is a huge concern then that the Jka specimens are non-reacting with the Diamed cards given the rare instances of the antibody in patients. Also, naturally-occurring Kidd antibodies are very rare. Further, there are multiple blood bank cards/methods in the region ie. Ortho gel, Grifols, Immucor, and we can view any of a patient's Kidd antibody history to provide antigen-negative red cells.
Thanks,
Robert
