16 DIAGNOSTIC TESTS The calculated ares are AU CW BC = 08613, AU CP CT = 0.8956. On the basis of the adopted level α = 0.05, based on the obtained value p=0.13032 we conclude that we cannot determine which of the parameters: WBC or PCT is be er for diagnosing bacteremia. ad2) PCT parameter is a s mulant (its value is high in bacteremia). In the course of the comparison of its diagnos c value for girls and boys we verify the following hypotheses: H0 : the area under ROC curve for P CTf = the area under ROC curve for P CTm , H1 : the area under ROC curve for P CTf ̸= the area under ROC curve for P CTm .
