Hi David, The card containing all of these reagents is produced by DiaMed, but I seem to remember that Anna (galvania) saying that it is only on sale in Europe. It is what we routinely use, but it must be remembered that we are a Reference Laboratory (something I forget myself sometimes when I'm posting on here, and answering a question from a Hospital Blood Banker) and so many of the samples referred have already been tested by either broad spectrum reagents or by monospecific anti-IgG and anti-C3d. Just occasionally, we receive a sample from a patient who is clinically showing a picture of WAIHA, but with a negative DAT at the hospital, that gives a positive DAT in our hands with anti-IgA only. I attach a not very good photograph so that you can see what the card looks like. :) IgA DAT.zip
