ACT Correlation Procedure

Since there's no lab equivalent for ACTs, we do meter-to meter correlations using the quality crosscheck samples. You can also use QC results- several normals and abnormals of the same lot numbers, across the different devices. 

We order verification samples for our Proficiency samples so that we can cover every section performing ACTs at least once each year.  Once we receive our proficiency results, we compare the results as we would correlation samples.  We end up with a correlation "study" 3 times annually without duplicating effort.
