out of 132 test portions were reported as positive (POD R of 0.0.39). A dLPOD C value of -0.02 with 95% confidence interval of (-0.15, 0.12) was obtained between the candidate and reference method, indicating no statistically significant difference was found by the study. A dLPOD CP value of 0.00 with 95% confidence intervals of (-0.04, 0.04) was obtained between presumptive and confirmed results indicating no statistically significant difference was found by the study. For the high inoculation level, 132 out of 132 test portions (POD CP of 1.00) were reported as presumptive positive by the candidate method with 130 out of 132 test portions (POD CC of 0.98) confirming positive. For the candidate method true positives, 130 out of 132 test portions (POD C of 0.98) were both presumptive positive and confirmed positive. For the reference method, 127 out of 132 test portions were reported as positive (POD R of 0.96). A dLPOD C value of 0.02 with 95% confidence interval of (-0.03, 0.09) was obtained between the candidate and reference method, indicating no statistically significant difference was found by the study. A dLPOD CP value of 0.02 with 95% confidence intervals of (-0.01, 0.04) was obtained between presumptive and confirmed results indicating no statistically significant difference was found by the study. For the non-inoculated controls, 0 out of 132 samples (POD CP of 0.00) produced a presumptive positive result by the candidate method with 0 out of 132 test portions (POD CC and POD C of 0.00) confirming positive. For the reference method, 0 out of 132 portions were reported as positive (POD R of 0.00). A dLPOD C value of 0.00 with 95% confidence interval of (-0.03, 0.03) was obtained between the candidate and reference method, indicating no statistically significant difference was found by the study. A dLPOD CP value of 0.00 with 95% confidence intervals of (-0.02, 0.02) was obtained between presumptive and confirmed results indicating no statistically significant difference was found by the study. Detailed results of the POD statistical analysis for the GENE-UP Salmonella method with traditional confirmation are presented in Table 2020.2B and Figures 2A – 2D.
