The Blood Testing Problem

Suppose that you have a large
population you wish to test for a
certain characteristic in their
blood or urine (for example, testing all
NCAA athletes for steroid use or all
US military personnel for a particular
disease). Each test will be either
positive or negative. In this problem,
we are assuming that there are no false
positive or false negative tests. Since
the number of individuals to be tested
is quite large, we can expect that the
cost of testing will also be large. How
can we reduce the number of tests
needed and thereby reduce the costs?
