<p>Determining diagnostic quality of diagnostic tests using measured values involves providing measured values from two diagnostic tests measured on patients with (positive) and without (negative) the illness to be diagnosed, determining for each cut-off pair and for measured values selected for those measured values belonging to patients who correctly/falsely tested positive or negative, and calculating discordance analysis characteristics (DAC) specificities for two diagnostic tests for each cut-off pair according to a equation as given in the specification. Determining diagnostic quality of diagnostic tests using measured values involves providing measured values from two diagnostic tests measured on patients with (positive) and without (negative) the illness to be diagnosed, selecting for each cut-off pairs all measured values that either lie above or below the associated cut-off for Tests 1 and 2, determining for each cut-off pair and for measured values selected for those measured values belonging to patients who correctly/falsely tested positive or negative, and calculating discordance analysis characteristics (DAC) specificities for two diagnostic tests for each cut-off pair according to a equation as given in the specification.</p> |
