7.1.1.4 Cross laboratory probability of detection (LPOD) – LPODs by matrix and concentration with 95% confidence intervals for candidate method 7.1.1.5 Difference of cross-laboratory probability of detection (dLPOD) – difference probability of detection is the difference between any two (presumptive and confirmed) results.

LPOD values.

7.1.1.5.1

Estimate dLPOD C

as the difference between the candidate

and reference LPOD values, include CIs.

7.1.1.5.2

Estimate dLPOD CP

as the difference between the

presumptive and confirmed LPOD values, include CIs. If the CI of a dLPOD does not contain zero then the

7.1.1.5.3

difference is statistically significant .
