# diagnostic odds ratio

*— The odds of someone with the target condition of interest having a positive diagnostic test divided by the odds of someone without the condition having a positive diagnostic test*

#### Synonyms:

DOR

#### Full forklaring:

The diagnostic odds ratio is a single indicator of how informative a diagnostic test is that is independent of the prevalence or pre-test probability of the target condition of interest (unlike diagnostic accuracy).

The diagnostic odds ratio ranges from zero to infinity. A diagnostic odds ratio of exactly one means that the test is equally likely to be positive whether someone has the condition or not.

Higher diagnostic odds ratios are indicative of better test performance.
