Has any of you validated the Grifols Gel card manually with Grifols screen cells and Ortho screen cells. and how did it go? Thanks

Interesting idea.  Sorry, I don't have an answer for you.

We crosscheck our 0.8% cells every month in the gel cards. We have Ortho cells and just test the new cells we receive and the current cells in use.  We have a diluted anti-D that gives a 1+ reaction to use as our anti-sera.  I would think that the same method could be used to check the Ortho cells against the Grifols cells.  Just test to see that the cells react as they should.

There are differences between the Ortho MTS system and Grifols DG gel system in terms of the amount of LISS found in the RBC reagents and gel cards.  

Speaking from the Grifols perspective, we have had customers try to validate the use of Ortho RBCs in DG gel cards and frequently these customers observe non-specific agglutination, indicating that there may be some incompatibility between how the reagents and gel cards are formulated.

why not just use grifols' cells?
