I'll assume you are doing Gel testing manually. I think you are wise to convert routine ABO/Rh and Antibody screen from tube testing to Gel testing.
To QC the antibody screen test using Surgiscreen and Anti-IgG Gel card, you need a positive and negative control cell for each screen cell vial. This can be accomplished in one (1) Anti-IgG Gel card.
To QC the A/B/D Monoclonal and Reverse Grouping card, you will need to test each reagent in the gel card with positive an negative controls (this will require a minimum of two cards). You can QC the two (2) Buffered Gel columns with anti-A + A1 cells, anti-A + B cells, anti-B + A1 cells, and anti-B + B cells using the same two A/B/D Monoclonal and Reverse Grouping cards.
You could use the A/B/D Gel card to confirm all donor unit types or you could use the A/B Gel card for non-group O Rh positive units, the Anti-A,B Gel card for all group O Rh positive units, and use the A/B/D Gel card for all units labeled Rh Negative. All these cards would require Day of Use QC.
You could use the A/B/D Monoclonal and Reverse Grouping Gel card or the A/B/D Monoclonal Grouping card for Cord Blood testing. These cards will not detect all weak D's. You will have to run Weak D testing on all Cord Bloods initially classified as Rh Negative.
There are other options based on your workload.
