DEF

A form of bias that occurs in the study of diagnostic test validity when the test result influences the decision whether to use the gold standard.

OBS

This bias can substantially distort the estimation of the validity of the test studied. It can be avoided if all the eligible subjects are consecutively verified using the gold standard, regardless of the result of the test studied, or if the subjects are selected on the basis of the results of the gold standard, before the results of the test studied are known.

DEF

Biais se produisant dans l’étude de la validité d’un test diagnostique lorsque le résultat du test influence la décision d’effectuer ou non le test de référence.

OBS

Ce biais peut fausser substantiellement l’estimation de la validité du test étudié. On peut l’éviter en soumettant au test de référence tous les sujets admissibles, et ce, de façon consécutive, sans égard au résultat du test étudié, ou en sélectionnant les sujets selon les résultats du test de référence avant que les résultats du test étudié soient connus.

OBS

biais de vérification; biais lié aux investigations; biais d’élaboration du diagnostic; biais lié au bilan clinique : termes et définition normalisés par l'Institut national d'excellence en santé et en services sociaux (INESSS) et le Bureau de la traduction.
