Please help.. I need to validate a manual dilution for an alinity analyte.

The current linearity goes up to 10.. we need our reference range to go up to 20. According to manufacturer we can do a dilution, but how do I validate it?? We are thinking spiking samples.

I’m just confused why we have to validate a manual dilution when the AMR itself isn’t changing and already validated
