Pool testing allows scientists to test samples more efficiently, analyzing many samples at once. To test samples more efficiently, the researchers used a technique called 'pooling.' That is essentially most of America's workforce. Samples came from six major metropolitan areas: San Francisco, Boston, Minneapolis, Los Angeles, New York City, and Seattle. If a pool tests positive, scientists then re-test smaller groups of samples included in the pool in order to find the positive one.
Pool testing allows re-testers to test flowers.

Pool testing allows re - testers to test flowers .
