  1. Sensitivity and specificity of a single diagnostic test in the presence of work-up bias.

    Article - En anglais

    A diagnostic test is put into routine use by being applied to a population with unknown test status and unknown disease status.

    All subjects with a positive test are then referred to a « gold standard » assessment for the disease.

    Subjects with a negative test are normally not referred to the « gold standard » assessment.

    In some cases, the investigators may refer a small random sample of subjects with a negative test to the « gold standard » assessment in order to determine if they really do not have the disease.

    If « gold standard » results are not available on an entire population.
