TEST REVIEW BIAS:
A bias relevant to studies of diagnostic accuracy. When the results of the diagnostic reference test (gold standard test) are known to the scientist at the time the test under study (index test) is interpreted1. Knowledge of the gold standard test results may influence the scores or decision made on the index test; especially if it is subjective. This knowledge could lead to better or worse agreement between the tests, depending on the context of the study.
Test Review Bias is the opposite of Diagnostic Review Bias. It is also related to Review Bias, and Diagnostic Suspicion Bias, and is sometimes used as a synonym for Clinical Review Bias2. Test Review Bias may be avoided by ensuring that scientists are blinded to all previous test results during a study. Also see: Diagnostic Review Bias, Clinical Review Bias, Diagnostic Suspicion Bias, Review Bias, Exposure Suspicion Bias, and Incorporation Bias.
