These utilities can be used to estimate true prevalence from survey data, using imperfect tests and a variety of methods.

- Sample size to estimate apparent or sero-prevalence
- Sample size to estimate true prevalence (at animal or herd-level)
- Estimated true prevalence with an imperfect test
- Simulated true prevalence with an imperfect test
- Bayesian estimation of true prevalence from survey testing with one test
- Bayesian estimation of true prevalence from survey testing with two tests
