Choose cells that can help rule out more than one antibody at a time in order to help decrease supply usage and tech prep time.
Example: Ruling out Anti-C, -Fyb, and -M if you have a suspected Anti-Jka
| Rh-Hr | Duffy | Kidd | MNSs |
Panel Cell | C | c | Fya | Fyb | Jka | Jkb | M | N |
9 | + | 0 | 0 | + | 0 | + | + | 0 |
10 | + | 0 | + | + | 0 | + | 0 | + |
11 | + | + | 0 | + | 0 | + | + | 0 |
12 | + | + | + | + | 0 | + | + | 0 |
Instead of running 3 separate cells to rule out the antibodies, you can choose one that is homozygous positive for M, C, Fyb and negative for Jka. Panel cell 9 works in this case.
If the only antibody that is present is Anti-Jka, then your test results should be negative. If the results are positive then further rule outs will be needed to determine what is present.
