On the contrary, measures of diagnostic accuracy are very sensitive to the characteristics of the population in which the test accuracy is being evaluated. What is also important is the fact that measures of a test performance are not fixed indicators of a test quality.

It is therefore of outmost importance to understand the meaning of different measures of diagnostic accuracy and to know how to interpret them and under what conditions they may be used. Some measures largely depend on the disease prevalence, while others are highly sensitive to the spectrum of the disease in the studied population. Some measures assess the global performance of a test, whereas others are related to its ability to detect or exclude the disease, or to the clinical significance of a positive or negative test result in a specific patient.ДЇurthermore, measures of a test performance are not fixed indicators of a test quality, but are very sensitive to the characteristics of the population in which the test accuracy is being evaluated.

While some measures are used to assess the discriminative property of the test, others are used to assess its predictive ability.Дiscriminative measures are mostly used by health-policy decision makers predictive measures are most useful for predicting the probability of a disease in an individual.

The discriminative ability of a diagnostic procedure is called diagnostic accuracy, and a number of quantitative measures out of which sensitivity and specificity are mostly used in the biomedical literature can express it.Д®ach diagnostic-accuracy measure relates to some specific aspects of a diagnostic procedure.
