Each diagnostic test whether it is a symptom, sign, laboratory, or radiological examination results in a change in the physician’s probability of disease, the posttest probability.

The degree to which a diagnostic test increases or decreases the probability of disease from pretest to posttest represents the clinical utility of the test as. It is a good indicator of the ability of a diagnostic test to confirm the absence of a disease when it is not present.
