Cost of individual vs. pooled testing. Cost per person of testing as a function of the percent positivity of the population tested. This model assumes an individual test cost of $25 and a pooled test cost of $40 due to additional processing steps required. Red line: individual testing, maroon line: pool size of 4, blue line: pool size of 6, gray line: pool size of 8, green line: pool size of 10, orange line: pool size of 16. Equation for pooled testing: ($40/pool size) + (% positivity × pool size × $25).
