Improvement of Sensitivity of Pooling Strategies for COVID-19

Figure 6

Improvement percentage of expected false negative rate of our procedure to the individual testing method. For ease of analyzing the relation of FNR among the considered methods, the estimation is done by assuming although it is a parameter adjustable in our model and the web interface. The -axis indicates FNR of individual testing method, the -axis represents FNR of the Dorfman’s method, and the cell value is the estimated percentage of improvement of FNR of our procedure to individual testing method. For example, when FNR (individual test) is 0.05 and FNR (pool) is 0.1, it gains an estimated 20% improvement upon the false negative rate by using our strategy, i.e., TFNR ≈ 0.04.
