Before revision: Group testing pools multiple samples together and performs tests on these pooled samples to discern the infected samples. It greatly reduces the number of tests , however, with a sacrifice of increasing false negative rates due to the dilution of the viral load in pooled samples.
After revision: Repeated asymptomatic screening for SARS-CoV-2 promises to control spread of the virus but would require too many resources to implement at scale. Group testing is promising for screening more people with fewer test resources: multiple samples tested together in one pool can be excluded with one negative test result. Existing approaches to group testing design for SARS-CoV-2 asymptomatic screening , however, with a sacrifice of increasing false negative rates due to the dilution of the viral load in pooled samples.
