A test may well be innovative (C), but this is not a necessity; if the
innovation improves how accurately those with and without disease can be separated
that is good, but if a standard test is accurate then no innovation is required.The
predictive value of a positive test (D) is heavily influenced by the prevalence (pre‐test
probability) of the disease in the screened population, so it is not a direct feature of the
quality of the test.This is measured by its sensitivity and specificity, both of which should
be high (E).
