Abstract

Under certain conditions, prevalence can be estimated by testing samples from individual members or by pooling samples from members into a group and by testing the sample from the group as a single unit. Pooled tests are more accurate than individual tests when P is less than 10%. Optimal group size is 1.6/P. Efficiency decreases slowly with suboptimal size and rapidly with overly large size.
