For many years the only way to test if a person had tuberculosis (TB) required a laboratory procedure that could take up to several weeks to produce a definite result. There are now DNA-based tests to detect TB that can be done in a couple of hours.
We have the following data on a DNA test for TB
If a person does not have TB then the DNA test always is negative.
If a person does have TB, then the DNA test will be positive 94% of the time.
Assume that we will use the test in Africa where the rate of incidence of TB is 450 per 100,000.
