Samples came from six major metropolitan areas: San Francisco, Boston, Minneapolis, Los Angeles, New York City, and Seattle. 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.' It was 25.4% in patients not hospitalized, 34.5% in those who were hospitalized without intensive care, and 27.2% in patients who had been critically ill. By comparison, that proportion was 7.3% in a group of healthy volunteers. The analysis pooled together 54 studies with a total of 77,758 participants.
