  • Analysis of false negative rates, false positive rates, sensitivity, and specificity.

    • Main Results:

    • A performance function can characterize qualitative and semi-quantitative methods and relate to quantitative methods.
    • Performance curves reveal key characteristics like sensitivity and specificity.
    • Uncertainty regions associated with methods can be determined from performance curves.

    Conclusions:

    • Consistent performance criteria are essential for reliable field screening and decision-making.
    • The proposed performance function unifies criteria across different method types.
    • Understanding performance characteristics and uncertainty improves the selection and use of field tests.
