If you are using irradiation indicators, what type are you using, how do you perform quality control on them, and how do you document your quality control?

Thanks!

We use Rad Sure indicators. The QC is performed with old and new together. We use 1 old indicator on a top of the unit of blood. we place 1 old and 1 new lot sideby side on the bottom of the bag. Run the cycle and compare the two bottom ones side by side. We peel the bottom ones off and place it on the QC log with lot # information and indicate on the log if QC was okay and or not. We save 2 indicators in an envelope for the lot that we just QC'd for the next lot.
