Said: We use two meters - one for the old lot of strips/controls and one for the new lot of strips/controls.  We only run linearity on the new lot of strips (and of course on new meters or for troubleshooting).

Said: We use multiple meters, at least two, to make the process quicker. We do not use every meter though, as we have 150. We only run linearity on new meters and/or if we are troubleshooting. 

Said: Thanks for responding, Erin and Jacqueline. Do you validate the QC and strips on one meter? We run them the new lots on all of our meters in conjunction with our linearity testing. It's a lot of testing at one time!
