1Ć57 Learning About the System
You can also obtain correlation data by parallel testing of patient samples that span
the reportable ranges on the new system and on the existing system or method.
Results from the new system are plotted against the existing system or method.
Typically, linear regression and least squares evaluation are used to compare
results. The slope and intercept of the regression line can be used to match the
results of the new system to an existing system or method. Refer to Appendix G,
Correlation Adjustment.
Refer to the Analyte Performance Verification Interpretive Guide, which is
provided by Bayer Diagnostics during the APV process, for more information
about the APV process.
