Well done. I totally agreed what Suszane Butch's comment about the methods comparsion especially for antibody identifcation methodologies. I think this checklist will make sense for instruments. In our hospital, we have two instruments (Galileo for routine samples and Echo mainly for stat samples). If one is down, then all samples run in the other one. It is important to ensure that it does not matter which instrument to use, the result is the same. I think the comparsion studies will ensure this.
