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

1Sensitivity- Ability of test to correctly identify those with disease x
1. ATrue
2. BFalse
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. ATrue
2. BFalse
5Negative predictive value (probability that person with -ve result has the disease) =?
1. A(d/c+d)
2. B(d/b+d)
6When identifying people with a very high risk disease, what tests do you use, and in what order?
1. AFirst 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
2. BFirst one that's highly specific (to not worry people who don't have it unecessarily) then one that's highly sensitive
7Prevalence = Those with disease/Total population
1. ATrue
2. BFalse
