Focus on Global Terminology

This month’s terms:

Diagnostic sensitivity: The proportion of patients with a well-defined clinical disorder whose test values are positive or exceed a defined decision limit (i.e., a positive result and identification of the patients who have a disease); NOTE 1 The clinical disorder must be defined by criteria independent of the test under consideration; NOTE 2 The European term “diagnostic sensitivity” is equivalent to the deprecated (discouraged) U.S. term “clinical sensitivity.” Editor's Note: In Europe, the term "clinical" applies mostly to clinical studies of drugs, under much more stringent conditions.
Diagnostic specificity: The proportion of subjects who do not have a specified clinical disorder whose test results are negative or within the defined decision limit; NOTE 1 It is the fraction of clinically true negative classifications divided by the sum of clinically true negative plus clinically false positive classifications; NOTE 2 The European term “diagnostic specificity” is equivalent to the deprecated (discouraged) U.S. term "clinical specificity." Editor's Note: In Europe, the term "clinical" applies mostly to clinical studies of drugs, under much more stringent conditions.
