We are currently getting the 500 mL bottle and just using 400mL.

Maybe I am confused...If you are performing Fya, Fyb, S, s (or any Coombs phase typing) in buffered gel cards, how does that work? It is my understanding that there is no anti-IgG in buffered gel cards. I know that the Buffered Gel Card's package insert says that it can be used for warm antibody ID, but without the anti-IgG how is that possible...for the Ab ID or Ag typing? Thanks!

Prior to understanding a "Super" DAT, I once told a physican that we would do a regular DAT for him and do it super well and super fast. (He didn't laugh.) However, I do now understand it a little better. It is useful when a physican is diagnosing a patient with an autoimmune disorder as this can be difficult when the patient's DAT is negative. The super DAT procedure can detect 50 IgG molecules attached to the red blood cell surface; whereas, the regular DAT can only detect 500 IgG molecules. Also, the super DAT can be helpful in diagnosing HDN or a transfusion reactions when the regular DAT is negative by identifying a very small population of cells with IgG attached.
