Table 4: Performance of MBS POCT in antibiotic susceptibility Accuracy, sensitivity, specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) were calculated according to Friedman et al. [21] for the MBS POCT compared to urine culture antibiograms for amoxicillin-clavulanic acid, ciprofloxacin and trimethoprim-sulfamethoxazole.
Accuracy Sensitivity Specificity PPV NPV
UBC+ amoxicillinclavulanic acid 52 % 92 % 26 % 44 % 83 %
UBC+ ciprofloxacin 84 % 93 % 25 % 89 % 33 %
UBC+ trimethoprimsulfamethoxazole 65 % 90 % 10 % 68 % 33 %
