Design outcomes

Primary

MeasureTime frame
The primary outcome is the sensitivity and specificity of combinatorial tapestry pooling technique as compared to individual testing, across various prevalence rates and degrees of pooling.Timepoint: baseline

Secondary

MeasureTime frame
Cost per individual for each of the three types of testing (for negative and positive tests) at different levels of poolingTimepoint: baseline;The sensitivity and specificity of each level of combinatorial tapestry pooling as compared to simple pooling at the same level.Timepoint: baseline;The sensitivity and specificity of the simple pooled technique as compared to individual technique, across various prevalence rates and degrees of poolingTimepoint: baseline
