Abstract:
Existing methods used to rank the value of individual screening markers in screening programmes are inadequate. We have developed a simple Screening Marker Index: (Screening Marker Index = Positive Predictive Value x Sensitivity). The Screening Marker Index proved to be superior to existing indices in ranking screening markers according to their ability to identify the conditions sought.
