In this chapter you will learn more about the main test parameters, how you can evaluate a diagnostic test and which strategy to choose to provide an answer to a specific diagnostic question.

If these themes are not familiar to you, we offer a “learning path” with the title “Concepts and strategies in diagnostics” which guides you through these topics. You will find several animated graphs and simulations which will help you to learn more about the theorem of Bayes and the significance of predictive values for choosing appropriate strategies fitting your diagnostic objectives. For the learning path, you will need approx. 40 minutes.
