When staff runs QC (same lot) on a new lot # of HR-ACT cartridges, what are you using for acceptable limits from one cartridge lot to another?
Thanks for your time!

I’m very interested in responses to your question. Currently, if the QC result is within the manufacturer’s range, we accept it.
I use a 20% evaluation limit for results.

That is how we determine new lot acceptability too. If QC passes, all is well.
I use a 10% agreement between the cartridge lots and I use literally the same QC vial tested simultaneously on 2 different instruments using the 2 different lots. That way there is no difference (theoretically) except the cartridge lot.
As for a new QC lot, those values (especially level 2) can seriously vary so if it's beyond 10% then I rerun it to verify and document the difference in values. That way I can explain a sudden QC shift to inspectors (and myself).
