Samples came from six major metropolitan areas: San Francisco, Boston, Minneapolis, Los Angeles, New York City, and Seattle. That is essentially most of America's workforce. A study published on Tuesday in PLoS Medicine suggests that boosting vitamin D levels with supplements would not help. 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.'
