Diagnostics refers to the investigation and identification of disease states in medicine. In diagnostic accuracy studies, it is also important to prespecify testable hypotheses such as minimum levels of sensitivity/specificity, positive/negative predictive value or AUC value, superiority or non-inferiority to another index tests. The difference between prospective and retrospective designs lies in the data collection.
