Population Demographics Gender Age Ethnicity
Environment Cultural aspects Geographic locations
Analytical Methods Reagents Procedures Temp Analytical Variables
Diagnostic Sensitivity frequency of abnormal or positive test results in individuals who have a selected disease
Specificity frequency with which a normal or negative test result is observed in individuals free of disease
predictive value is a measure of whether an abnormal test result really indicates that the patient has a particular disease or whether a normal test result correctly excludes the existance of a disease in the patient
Efficiency of test described as the probability that a test reslt, whether positive or negative, correctly classifies the presence or absence of disease
%Sensitivity = TP / (TP+FN)
%Specificity = TN / (FP+TN)
%Positve Predictive value = TP / (TP+FP)
%Negative Predictive Value = TN / (TN+FN)
% Efficiency = (TP+TN) / (TP+FP+FN+TN)
