Effect of prevalence rate on the number of samples that require repeat testing. (A) Visual display of the first predicted plates for 4% and 12% prevalence in the testing population. The 12% prevalence illustrates the increased likelihood of multiple positives being pooled randomly into the same well. (B) 20 plates were predicted for each prevalence level using random number generation to examine the effect of prevalence on the number of samples that required reanalysis. The colors indicate the number of samples that require rerun of samples independently to identify the positive sample based on 5-sample pools.
