Method Comparison

The comparison table contains the following columns:

  • Trendable?: Indicates whether both methods use the same component code and results are trendable in Epic.
  • Bias: The average absolute difference between Roche and Beckman results. A positive value means Roche results are higher on average.
  • Percent Bias: Blue shading and bars extending left indicate negative bias (Beckman higher on average); orange shading and bars extending right indicate positive bias (Roche higher on average). Longer bars indicate greater magnitude.
  • Slope: The slope of the linear regression of Roche onto Beckman, representing proportional bias between the methods. “Not comparable” indicates that the methods were too poorly correlated for direct patient-result comparison.
  • R2 (Coefficient of Determination): How closely the regression fits the paired results.

These data can help when comparing results across platforms, but should not be used to convert a result directly from one method to the other.
