HI all. we are about to validate the echo as an IRL since so many of our customers use it. We will continue to test by tube as we know it best, but sometimes we need to see what others are seeing that we are not in tube. I am looking to set our concordance testing criteria and was wondering what others who have already validated have observed in their testing. I thought this might be quicker than calling around. I am specifically looking to see correlations regarding antibody id. any response would be greatly appreciated.
