A simple calculator to convert the sensitivity and specificity of a SARS-CoV-2 rapid antigen test, as listed at https://diagnosticsglobalhealth.org/, into concrete numbers of true and false test results, given the current incidence rate in the population.
The user provides
- Incidence
- Sensitivity
- Specificity
The calculator then displays the expected number of
- True Positive
- True Negative
- False Positive
- False Negative
results if 1000 people are tested, along with the corresponding
- Positive Predictive Value
- Negative Predictive Value
