Maternal alloantibody, not detected in baby - how long for antigen negative units
We might be the "Odd-Man-Out" - but, if the mom has an antibody and the DAT is negative on the cord sample, we don't test the plasma. If they order a neonate type and screen and the screen is negative, we don't give antigen negative units.............🙀................unless there is clinical evidence of hemolysis our Med Dir says it's warranted.

Plasma transfusions
My question would be - how strong was the pre-transfusion reactivity? If it was only 1-2+ in SP / and the patient isn't a "larger" person, I personally would suspect that the antibody titer was diluted to such a degree that SP did not pick it up anymore....... (but I REALLY don't like SP.....it's just too wishy-washy.....JMHO)

Ortho to immucor reagents
Not sure that there is a specific number. We just validated some Grifols antisera and ran 20 comparisons.

Eliminating Immediate spin for cold agglutinins
At our facility, we have to do a cold adsorption IF the cold auto interferes with the reverse and/or ISXM. Since testing with "neat" plasma is our standard of practice, we would still report the XM as incompatible and send it out with a release stating the incompatibility was due to an autoantibody. We are not "allowed" to prewarm away IS reactions. 🥶 IF we prewarm - it's only if the cold has a high thermal amplitude and causes interference after 37deg incubation / antiglobulin phase...........but that's just us.........

Gel vs tube for DARA patients
Once our patients show panreactivity in GEL, we automatically switch them to PEG screens which are negative 95% of the time. We stop doing gel all together. We don't test with DTT treated cells until the PEG screen comes up pos. Then, if the screen is NEG with DTT treated cells, we give K neg units with a signed release.
