Example of Summary Table for Evaluation of Percent Agreement.

In the table:a = number of specimens tested positive by both Method 1 and Method 2.b = number of specimens tested positive by Method 1 and negative by Method 2.c = number of specimens tested negative by Method 1 and positive Method 2.d = number of specimens tested negative by both Method 1 and Method 2.The following statistics will be calculated:•Overall Percent agreement between Methods = .•Positive Percent Agreement between Methods = .•Negative Percent Agreement between Methods = .95% confidence intervals for the above percent agreements will be calculated using methods described in CLSI EP12-A, User Protocol for Evaluation of Qualitative Test Performance; Approved Guideline, 2002.
