Standards require that RBCs shall be prepared by sparating the red cells from the plasma portion of blood using a method known to result in a final HCT of < 80%.

We perform monthly QC and have a standard of 90% of units must be < 80%. I do not have a reference for this . Does anyone have a different standard and what reference did you use?

Also, do you discard units of RBC that do not meet this criteria?

We use CPDA-1 as our anticoagulant.

You are meeting the AABB Standard. The reference in the 22nd edition is 5.7.5.1. QC units that do not met this standard are remixed, resampled and tested one time. QC failures are not released. An investigation of the failure is also started.

I don't have a reference for the 90%.

Hope that helps.
