When identifying people with a very high risk disease, what tests do you use, and in what order?

First one that's highly sensitive (so we don't miss anyone who does have it) and then one that's highly specific to remove those that don't

First one that's highly specific (to not worry people who don't have it unecessarily) then one that's highly sensitive

1. ARichtig
2. BFalsch
2What is the equation for sensitivity?
1. A(a/a+c) x 100
2. B(a/a+b) x 100
3Specificity
1. AAbility of new test to correctly identify those without disease
2. BTest that best predicts disease prevalence
3. CProbability that person with +ve result has disease
4The gold standard is the test that best predicts disease prevalence
1. ARichtig

1. A(d/c+d)
2. B(d/b+d)
